摘　　要：目的 探讨卵巢卵泡膜细胞瘤的影像表现及临床特征,以提高对该肿瘤的认识及诊断水平。方法 回顾性分析6例经手术病理证实的卵泡膜细胞瘤的CT、 MRI影像学、临床及病理相关资料,并分析病变的影像学特征。结果 6例卵泡膜细胞瘤表现为边界清晰的囊实性肿块,4例MRI检查病变实性部分T1WI等或稍低信号,T2WI呈稍低或稍高信号,2例CT检查显示病变密度不均的等或低密度影,囊性部分多发为絮状、裂隙状、斑点状及囊状,MRI絮状囊变较为典型;病变实性部分DWI呈高信号,增强扫描轻度强化。6例病变均合并盆腔积液。结论 卵泡膜细胞瘤有一定的影像学特征,若发现卵巢囊实性肿瘤,T2WI见絮状囊变典型改变,实性成分于T2WI呈稍低或稍高信号,结合患者临床病史,应考虑到该肿瘤的诊断。Objective To investigate the imaging findings and clinical characteristics of ovarian thecoma to improve the understanding and diagnosis accuracy of this kind of tumor.MethodsRetrospectively studied the images and clinical data of six ovarian thecoma which confirmed by surgery and pathology,and the imaging characteristics of the lesions were analyzed.ResultsWe totally find six tumors in six patients.Six cases of ovarian thecoma showed well-defined cystic and solid masses.Four cases showed isointensity or slightly hypointensity on T1WI and slightly hypointensity or slightly high intensity on T2WI in the solid part of the lesions on MRI.Two cases showed heterogeneous equal or low density on CT,and the cystic part was mostly floccular,fissured,spotty,and cystic.The floccular cystic change on MRI was typical.The solid part of the lesions showed high intensity on DWI and mild enhancement on contrast-enhanced scans.All six lesions were associated with pelvic effusion.ConclusionThere are some specific imaging features of ovarian thecoma.According to clinical history,ovarian tumors with floccular cystic degeneration and solid components which show hypointensity or slightly high intensity on T2WI should be considered to the diagnosis of ovarian thecoma.
