摘　　要：目的:探讨阔韧带平滑肌瘤(BLL)在低场MRI中的不典型表现及其病理学基础,以提高BLL的诊断及鉴别诊断水平。材料与方法:回顾性分析经手术病理证实的13例不典型BLL患者的MRI表现和病理资料。结果:13例不典型BLL,3例以囊性成分为主,包绕不规则实性成分(实性成分T2WI呈高信号),增强扫描瘤实质不均匀明显强化,病理上肿瘤由纵横交错的胶原纤维束、梭形细胞束构成,伴有程度不同的玻璃样变性、透明变性;4例(T2WI上呈低信号)轻度强化,病理上肿瘤内平滑肌细胞较少,而胶原纤维组织较多;9例在T2WI上呈高信号(均为明显强化),病理上肿瘤由较多平滑肌细胞构成,且细胞胞体大,含水量多,间质少。结论:BLL在低场MRI上具有多种不典型的表现,熟悉其病理学基础有助于提高BLL的诊断与鉴别诊断水平。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.
