摘要
目的分析卵巢性索间质肿瘤(OSCSTs)的影像学特征,以提高其术前正确诊断率。方法回顾性分析32例经手术病理证实的OSCSTs术前影像学资料,总结其影像学特征并进行鉴别诊断分析。结果32例患者中6例行CT检查,26例行磁共振(MRI)检查。CT表现:均为单侧实性肿块,平扫类似子宫肌层密度,增强后轻度强化。MRI表现:均为单侧肿块,以实性成分为主,部分的囊实性肿块,实性成分T1WI等信号为主,T2WI信号复杂,10例(38.46%)等信号,6例(23.08%)低信号,10例(38.46%)混杂信号,增强后轻度强化。DWI上22例(84.62%)表现为高信号,4例(15.38%)表现为混杂信号。结论OSCSTs影像表现有一定的特征性,有利于术前正确诊断。
Objective To analyze the image features of the ovarian sex cord-stromal tumors(OSCSTs)so as to improve the accuracy of preoperative diagnosis.Methods The preoperative imaging date of 32 patients with OSCSTs confirmed by surgery and pathology were analyzed retrospectively,summarized its imaging features and conducted differential diagnosis analysis.Results Among these 32 patients,CT was performed in 6 cases,while MRI was performed in 26 cases.CT findings:unilateral solid tumor,the plain images were similar to the density of the myometrium,and the contrast-enhanced CT images showed mild enhancement.MRI findings:unilateral mass,solid cystic masses with most solid components,most solid components in T1WI showed equal signal,T2WI showed mixed signal,10 cases(38.46%)showed equal signal,6 cases(23.08%)showed lower signal,10 cases(38.46%)showed mixed signal,mild enhancement.22 cases(84.62%)showed high signal on DWI,and 4 cases(15.38%)showed mixed signal.Conclusion The imaging findings of OSCSTs have some characteristics,which is useful to the correct diagnosis before operation.
