Objective：To study value and findings of Magnetic resonance imaging diagnoses of the broad ligament leiomyoma. Methods：Retrospectively analysis the findings of magnetic resonance of 13 cases the broad ligament leiomyoma. All were proved by operative and pathological confirmation. Results：Of the 13 patients, these tumors located at the right lateral of uterus （n=4,4/13） ,the left （n=8,8/13） ,bilateral （n= 1,1/13）. The tumors were similar to pellet or ellipse shape in 10 cases and irregular shape in 3 cases. The diameter of tumors be more larger 5cm were in 11 cases （11/13）. These tumors had a signal of intermediate or slightly low intensity on T1-weighted images, while on T2-weighted images a intermediate in signal intensity of the masses,with dot and shuttle-strip hyper-intense areas were in 11 cases and with larger fluidify patchy were in 2 cases, The masses had obviously contrast enhanced with patchy non-enhanced areas after intravenous Gd-DTPA injection. MR demonstrated masses with integrity capsule and clearly border in 10 cases and not in 3 cases. The capsules were more clear and non-enhanced. Conclusion： A characteristic feature of the broad ligament leiomyoma in MR were found the larger,solid or more solid masses of pevil and extrauterine with capsule, these tumors had a signal of intermediate or slightly low intensity on T1-weighted images and a intermediate in signal intensity on T2-weighted images with dot and shuttle-strip hyper-intense areas often. MR possesses good soft tissue resolution, multi-direction imaging technique, which can demonstrate the capsule,inner structure of the tumor. These help to the confirm diagnoses.
