【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。
[Abstract]:Objective: to investigate the atypical features and pathological basis of leiomyoma of broad ligament in low field MRI in order to improve the diagnosis and differential diagnosis of BLL. Materials and methods: the MRI findings and pathological data of 13 patients with atypical BLL confirmed by surgery and pathology were retrospectively analyzed. Results in 13 cases of atypical BLL, 3 cases were composed of cystic components and irregular solid components (solid component T2WI showed high signal intensity, enhanced tumor was not homogeneous and enhanced obviously. Pathologically, the tumor was composed of crisscross collagenous fiber bundles and fusiform cell bundles. There were 4 cases of hyaline degeneration with hyaline denaturation with low signal intensity on T _ 2WI) and slight enhancement with less smooth muscle cells in the tumor pathologically. However, there were more collagen fibers in 9 cases with high signal intensity on T2WI (all of them were obviously enhanced). The tumor was composed of more smooth muscle cells in pathology, with large cell body, more water content and less interstitial matter. Conclusion there are many atypical manifestations in low field MRI. It is helpful to improve the diagnosis and differential diagnosis of BLL by familiar with the pathological basis.
