摘　　要：目的探讨精囊腺原发性肿瘤的MRI表现,以提高临床对精囊腺病变的诊断水平。方法对9例经手术病理证实的精囊腺原发性肿瘤的MRI资料,结合文献进行回顾性分析。结果孤立性纤维瘤4例,实性或囊实性,实性成分表现为T_(1)WI低信号,T_(2)WI高信号,增强扫描实性成分中度至明显强化。炎性肌纤维母细胞瘤2例,T_(1)WI、T_(2)WI均呈稍低或等信号,其内可见水样信号,增强扫描实性成分呈渐进性强化。神经鞘瘤2例,T_(1)WI呈等及稍高信号,T_(2)WI呈混杂信号,增强扫描实性成分渐进性强化。腺癌1例,呈多房囊状液体信号,增强扫描囊壁及分隔轻度强化。结论MRI有助于在术前判断精囊腺肿瘤的性质及肿瘤与周围组织结构的关系,为临床治疗方案制定提供指导。Objective To explore the MRI features of primary tumors of the seminal vesicle gland,to improve the clinical diagnostic level of seminal vesicle gland lesions.Methods MRI data of 9 cases of primary tumors of the seminal vesicle gland confirmed by surgery and pathology were retrospectively analyzed in conjunction with literature.Results The solitary fibrous tumor was found in 4 cases,which was solid or cystic-solid.The solid components showed low signal intensity on T_(1)WI and high signal intensity on T_(2)WI,and the solid components were moderate to obviously enhanced after enhancement.The inflammatory myofibro-blastic tumor was found in 2 cases,T_(1)WI and T_(2)WI showed a slightly low or equal signal,and showed a watery signal in it,and the solid components showed progressive enhancement on the enhanced scan.Neurilemmoma was found in 2 cases,T_(1)WI showed iso-and slightly high signal intensity,T_(2)WI showed mixed signal intensity,and solid components gradually enhanced during the contrast-enhanced scan.Adenocarcinoma was found in 1 case,which showed a multilocular cystic fluid signal with slight enhancement of the cyst wall and septum.Conclusion MRI is helpful to diagnose the nature of seminal vesicle gland tumor and the relationship between the tumor and surrounding tissue structure before the operation,and guide clinical treatment.
