卵巢腺纤维瘤临床及MRI特征:21例分析

Clinical and MRI features of ovary adenofibroma:Analysis of 21 cases

目的分析卵巢腺纤维瘤(OAF)临床及MRI特征。方法回顾性分析21例经手术病理证实的OAF患者临床资料及MRI表现。结果21例中,15例无症状,4例腹痛,2例腹胀;18例肿瘤标志物正常,3例CA125升高。MRI上,OAF可表现为实性肿块、囊实性肿块及多囊性肿块。实性肿块T2WI多为低信号及极低信号,增强后轻至中等强化;囊实性肿块T2WI见多囊伴极低信号实性部分及分隔,增强扫描无强化或仅轻度强化;多房囊性肿块T2WI囊壁及分隔呈低信号,增强后分隔轻度强化。结论OAF常无特征性临床表现,肿瘤指标多为阴性,MRI特征有助诊断。

Objective To observe clinical and MRI features of ovary adenofibroma(OAF).Methods Clinical and MRI data of 21 patients with OAF confirmed by surgery and pathology were retrospectively analyzed.Results Among 21 cases,15 were asymptomatic,while 4 cases complained of abdominal pain and 2 cases of abdominal distension.CA125 increased in 3 cases,while remained normal in 18 cases.OAF displayed as solid mass,solid cysts or polycystic masses on MRI.Most solid masses showed low signals or bottom signals on T2 WI with light to medium enhancements.The solid parts of solid cysts showed very low signals of the polycystic and cystic separation on T2 WI without or only slight enhancements.T2 WI of the multi-sac cystic masses showed low signal of the wall and the separation with slight enhancement.Conclusion OAF patients often had no characteristic symptoms,and tumor markers were mostly negative.MRI features were helpful to diagnosis of OAF.
