MORGAN STANLEY INSURED MUNICIPAL INCOME TRUST
LETTER TO THE SHAREHOLDERS o OCTOBER 31, 2002

DEAR SHAREHOLDER:

During the 12 months ended October 31, 2002, U.S. economic indicators fluctuated
between stronger and weaker growth. The economy continued to recover from
recession and the aftermath of September 11. Real gross domestic product (GDP)
accelerated to an annual rate of 5.0 percent in the first quarter of 2002. In
the spring, the economy began to send mixed signals and the recovery lost
momentum. Weakness in manufacturing and capital spending combined with
corporate-accounting scandals and geopolitical turmoil to slow GDP to a 1.3
percent annual rate in the second quarter. The strongest consumer spending of
the year and the restocking of inventories led to 4.0 percent annual growth in
the third quarter.

As the economy gained strength in the first few months of 2002, a general
consensus developed that the Federal Reserve Board would begin to tighten
monetary policy and raise short-term interest rates. The bond market reacted to
these concerns in March and yields rose. By late spring, however, the consensus
shifted to favoring bonds as labor market and capital-spending indicators
remained soft and new disclosures on corporate ethics spurred a flight to
quality. Most importantly, the Federal Reserve changed its monetary policy bias
from neutral toward one of easing. The market's expectations of eventual rate
hikes were scaled back and bonds rallied. A mid-October surge in the equity
markets created a downdraft in bond prices. However, renewed concerns about the
economy helped bond prices improve by month-end. On November 6, 2002, the
Federal Reserve lowered the federal funds rate from 1.75 to 1.25 percent. This
marked the first change by the central bank in nearly one year.

MUNICIPAL MARKET CONDITIONS

The economic environment and unsettled equity markets lowered municipal yields
to levels last seen in the 1960s. The yield on the 30-year insured municipal
bond index ranged from a high of 5.43 percent in March to a low of 4.74 percent
in September. The index yield stood at 4.96 percent at the end of October 2002.
Throughout the period the slope of the municipal yield curve remained steep. The
yield pickup for extending maturities from 1 to 30 years averaged 350 basis
points.

The ratio of municipal yields as a percentage of U.S. Treasury yields is used as
a gauge of the relative value of municipals. The ratio of 30-year insured
municipal bond yields to 30-year Treasuries fell from 98 percent in December
2001 to 94 percent in March. As municipals lagged the summer rally in
Treasuries, the ratio jumped to 102 percent in September but declined to 99
percent by the end of October. These levels imply that municipals are cheap
relative to Treasuries.

State and local governments took advantage of lower interest rates to refinance
outstanding debt in a manner similar to homeowners refinancing their mortgages.
Refinancing activity contributed to a surge in municipal bond underwriting, and
long-term volume increased 27 percent to a record $292 billion in the

first ten months of 2002. Refunding issues represented almost one-quarter of the
total. California, Florida, New York, and Texas, the largest states in terms of
issuance, represented 40 percent of the national volume. Issuance is on track to
raise calendar year 2002's volume to more than $325 billion.

MORGAN STANLEY INSURED MUNICIPAL INCOME TRUST
LETTER TO THE SHAREHOLDERS o OCTOBER 31, 2002 CONTINUED

Monthly dividends for the fourth quarter of 2002 were declared in September.
Beginning with the October payment the monthly dividend was increased from
$0.0675 to $0.075 per share. The new dividend reflects the level of the Trust's
undistributed net investment income and projected earnings power. The Trust's
level of undistributed net investment income was $0.187 per share on October 31,
2002, versus $0.086 per share last year.

PORTFOLIO STRUCTURE

The Trust's total net assets of $551 million, including Auction Rate Preferred
Shares (ARPS), were diversified among 14 long-term sectors and 79 credits. At
the end of October the portfolio's average maturity was 19 years. Average
duration, a measure of sensitivity to interest-rate changes, was 4.9 years. The
accompanying charts provide current information on the portfolio's credit
enhancements, maturity distribution and sector concentrations. Optional call
provisions by year and their respective cost (book) yields are also shown.

THE IMPACT OF LEVERAGING

As discussed in previous reports, the total income available for distribution to
common shareholders includes incremental income provided by the Trust's
outstanding ARPS. ARPS dividends reflect prevailing short-term interest rates on
maturities normally ranging from one week to one year. Incremental income to
common shareholders depends on two factors. The first factor is the amount of
ARPS outstanding, while the second is the spread between the portfolio's cost
yield and ARPS expenses (ARPS auction rate and expenses). The greater the spread
and the amount of ARPS outstanding, the greater the amount of incremental income
available for distribution to common shareholders. The level of net investment
income available for distribution to common shareholders varies with the level
of short-term interest rates. ARPS leverage also increases the price volatility
of common shares and has the effect of extending portfolio duration.

During the fiscal year, ARPS leverage contributed approximately $0.16 per share
to common share earnings. The Trust's five ARPS series totaled $155 million and
represented 28 percent of total net assets. In January 2002, ARPS series 4 was
extended until January 2004 at a yield of 2.47 percent. In July 2002, series 3
was extended until July 2004 at a yield of 2.20 percent. The yield on the
Trust's three weekly series ranged between 0.90 and 2.47 percent.

LOOKING AHEAD

The Federal Reserve Board's cautious approach toward an eventual rate tightening
earlier this year helped stabilize the fixed-income markets. In fact, the Fed's
current willingness to be accommodative resulted in a major bond rally during
the second and third calendar quarters. We believe that the yields on tax-exempt
securities continue to favor municipal bonds as an attractive choice for
tax-conscious investors. For many investors, the taxable equivalent yields
available on municipal bonds offer a significant advantage.

MORGAN STANLEY INSURED MUNICIPAL INCOME TRUST
LETTER TO THE SHAREHOLDERS o OCTOBER 31, 2002 CONTINUED

The Trust's procedure for reinvestment of all dividends and distributions on
common shares is through purchases in the open market. This method helps support
the market value of the Trust's shares. In addition, we would like to remind you
that the Trustees have approved a procedure whereby the Trust may, when
appropriate, purchase shares in the open market or in privately negotiated
transactions at a price not above market value or net asset value, whichever is
lower at the time of purchase. The Trust may also utilize procedures to reduce
or eliminate the amount of outstanding ARPS, including their purchase in the
open market or in privately negotiated transactions. During the 12-month period
ended October 31, 2002, the Trust purchased and retired 996,500 shares of common
stock at a weighted average market discount of 8.17 percent.

We appreciate your ongoing support of Morgan Stanley Insured Municipal Income
Trust and look forward to continuing to serve your investment needs.


Very truly yours,

MORGAN STANLEY INSURED MUNICIPAL INCOME TRUST
NOTES TO FINANCIAL STATEMENTS o OCTOBER 31, 2002

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Insured Municipal Income Trust (the "Trust") is registered under
the Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. The Trust's investment objective is to provide
current income which is exempt from federal income tax. The Trust was organized
as a Massachusetts business trust on March 12, 1992 and commenced operations on
February 26, 1993.

The following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS - Portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service uses
both a computerized matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions,
trading characteristics and other features deemed to be relevant. Short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. ACCOUNTING FOR INVESTMENTS - Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

C. FEDERAL INCOME TAX POLICY - It is the Trust's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable and nontaxable
income to its shareholders. Accordingly, no federal income tax provision is
required.

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS - Dividends and distributions to
shareholders are recorded on the ex-dividend date. The amount of dividends and
distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification. Dividends and distributions which
exceed net investment

MORGAN STANLEY INSURED MUNICIPAL INCOME TRUST
NOTES TO FINANCIAL STATEMENTS o OCTOBER 31, 2002 CONTINUED

income and net realized capital gains for financial reporting purposes but not
for tax purposes are reported as dividends in excess of net investment income
or distributions in excess of net realized capital gains. To the extent they
exceed net investment income and net realized capital gains for tax purposes,
they are reported as distributions of paid-in-capital.

E. USE OF ESTIMATES - The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures.
Actual results could differ from those estimates.

2. INVESTMENT MANAGEMENT AGREEMENT

Pursuant to an Investment Management Agreement with Morgan Stanley Investment
Advisors Inc. (the "Investment Manager"), the Trust pays a management fee,
calculated weekly and payable monthly, by applying the annual rate of 0.35% to
the Trust's weekly net assets including preferred shares.

3. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES

The cost of purchases and proceeds from sales of portfolio securities,
excluding short-term investments, for the year ended October 31, 2002
aggregated $92,424,658 and $131,199,040, respectively. Included in the
aforementioned are sales of $2,937,720 with other Morgan Stanley Funds, which
are affiliates of the Investment Manager.

Morgan Stanley Trust, an affiliate of the Investment Manager, is the Trust's
transfer agent. At October 31, 2002, the Trust had transfer agent fees and
expenses payable of approximately $8,850.

The Trust has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Trust who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended October 31, 2002
included in Trustees' fees and expenses in the Statement of Operations amounted
to $6,309. At October 31, 2002, the Trust had an accrued pension liability of
$47,223 which is included in accrued expenses in the Statement of Assets and
Liabilities.

4. PREFERRED SHARES OF BENEFICIAL INTEREST

The Trust is authorized to issue up to 1,000,000 non-participating preferred
shares of beneficial interest having a par value of $.01 per share, in one or
more series, with rights as determined by the Trustees, without approval of the
common shareholders. The Trust has issued Series 1 through 5 Auction Rate
Preferred Shares ("Preferred Shares") which have a liquidation value of $50,000
per share plus the redemption premium, if any, plus accumulated but unpaid
dividends, whether or not declared, thereon to the date of distribution. The
Trust may redeem such shares, in whole or in part, at the original purchase
price of $50,000 per share plus accumulated but unpaid dividends, whether or
not declared, thereon to the date of redemption.

------------
 *  As of October 31, 2002.
**  For the year ended October 31, 2002.

Subsequent to October 31, 2002 and up through December 6, 2002, the Trust paid
dividends to each of the Series 1 through 5 at rates ranging from 1.15% to
2.95% in the aggregate amount of $386,034.

The Trust is subject to certain restrictions relating to the preferred shares.
Failure to comply with these restrictions could preclude the Trust from
declaring any distributions to common shareholders or purchasing common shares
and/or could trigger the mandatory redemption of preferred shares at
liquidation value.

The preferred shares, which are entitled to one vote per share, generally vote
with the common shares but vote separately as a class to elect two Trustees and
on any matters affecting the rights of the preferred shares.

5. COMMON SHARES OF BENEFICIAL INTEREST

Transactions in common shares of beneficial interest were as follows:



                                                                                                               CAPITAL

MORGAN STANLEY INSURED MUNICIPAL INCOME TRUST
NOTES TO FINANCIAL STATEMENTS o OCTOBER 31, 2002 CONTINUED

6. FEDERAL INCOME TAX STATUS

During the year ended October 31, 2002, the Trust utilized approximately
$5,576,000 of its net capital loss carryover. At October 31, 2002, the Trust
had a net capital loss carryover of approximately $504,000 which will be
available through October 31, 2004 to offset future capital gains to the extent
provided by regulations.

As of October 31, 2002, the Trust had temporary book/tax differences primarily
attributable to book amortization of discount on debt securities and dividend
payable to preferred shareholders and permanent book/tax differences
attributable to tax adjustments on debt securities sold by the Trust. To
reflect reclassifications arising from the permanent differences, accumulated
undistributed net investment income was charged and accumulated net realized
loss was credited $25,139.

7. DIVIDENDS TO COMMON SHAREHOLDERS

On September 24, 2002, the Trust declared the following dividends from net
investment income:



          AMOUNT            RECORD               PAYABLE
        PER SHARE            DATE                 DATE
      -------------   ------------------   ------------------
                                     
      $  0.075        November 8, 2002     November 22, 2002
      $  0.075        December 6, 2002     December 20, 2002


8. EXPENSE OFFSET

The expense offset represents a reduction of the custodian fees for earnings on
cash balances maintained by the Trust.

9. RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS

The Trust may invest a portion of its assets in residual interest bonds, which
are inverse floating rate municipal obligations. The prices of these securities
are subject to greater market fluctuations during periods of changing prevailing
interest rates than are comparable fixed rate obligations.

At October 31, 2002, the Trust held positions in residual interest bonds having
a total value of $30,302,169, which represents 7.7% of the Trust's net assets
applicable to common shareholders.

10. CHANGE IN ACCOUNTING POLICY

Effective November 1, 2001, the Trust has adopted the provisions of the AICPA
Audit and Accounting Guide for Investment Companies, as revised, related to
premiums and discounts on debt securities. The cumulative effect of this
accounting change had no impact on the net assets of the Trust, but resulted in
a $110,763 increase in the cost of securities and a corresponding increase to
undistributed net investment income based on securities held as of October 31,
2001.


                                       22


MORGAN STANLEY INSURED MUNICIPAL INCOME TRUST
NOTES TO FINANCIAL STATEMENTS o OCTOBER 31, 2002 CONTINUED

The effect of this change for the year ended October 31, 2002 was to increase
net investment income by $17,252; increase unrealized appreciation by $7,887
and decrease net realized gains by $25,139. The Statement of Changes in Net
Assets and the Financial Highlights for prior periods have not been restated to
reflect this change.

11. CHANGE IN FINANCIAL STATEMENT CLASSIFICATION FOR PREFERRED SHARES

In accordance with the provisions of EITF D-98, "Classification and Measurement
of Redeemable Securities", effective for the current reporting period, the
Trust has reclassified its Preferred Shares out of the composition of net
assets section on the Statement of Assets and Liabilities. In addition,
dividends to preferred shareholders are now classified as a component of
operations on the Statement of Operations, the Statement of Changes in Net
Assets and the Financial Highlights. Additionally, the categories of
investments on the Portfolio of Investments are shown as a percentage of net
assets applicable to common shareholders. Prior year amounts have been
reclassified to conform to this period's presentation. This change has no
impact on the net assets applicable to common shareholders of the Trust.

MORGAN STANLEY INSURED MUNICIPAL INCOME TRUST
INDEPENDENT AUDITORS' REPORT


TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
MORGAN STANLEY INSURED MUNICIPAL INCOME TRUST:


We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Insured Municipal Income Trust (the "Trust"), including the portfolio
of investments, as of October 31, 2002, and the related statements of
operations for the year then ended and changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of
the five years in the period then ended. These financial statements and
financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures
included confirmation of securities owned as of October 31, 2002, by
correspondence with the custodian and brokers. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Morgan Stanley Insured Municipal Income Trust as of October 31, 2002, the
results of its operations for the year then ended, the changes in its net
assets for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended, in conformity
with accounting principles generally accepted in the United States of America.
