Abstract：Objective: To investigate the atypical appearances of broad ligament leiomyoma(BLL) on the low field MRI and pathological basis, and to improve the diagnosis and differential diagnosis of the BLL. Methods: The MRI manifestations and pathological data of 13 cases of BLL proved by pathology were analyzed retrospectively. Results: It showed high signal in T2WI and obviously inhomogeneous enhancement in 3 cases of cystic masses with irregular solid component, and their manifestations of pathology were smooth muscle cells were less but with more collagen fibers in the tumor. It showed slightly enhancement and low signal in T2WI in 4 cases, which showed that the smooth muscle cells were less but with more collagen fibers in the tumor. It showed high signal in T2WI and enhanced obviously in 9 cases, which the tumor was composed of many smooth muscle cells with big cell body and deep dyeing. There was much water and a little of interstitial. Conclusion: There are many atypical performance of BLL on low field MRI. It contributes to improve the diagnosis and differential diagnosis by mastering the pathological basis of BLL.
