摘　　要：目的探讨卵巢卵泡膜细胞瘤的MR表现特点与临床特征分析,以提高对该肿瘤的认识及诊断水平。方法对收治的14例经病理证实的卵巢卵泡膜细胞瘤MR资料、病理及临床特征分析,观察肿瘤MR影像特征与临床、病理特点的表现进行相关性分析。结果 MR平扫肿块实质性为主,部分肿瘤内可有囊变区,于T_2WI压脂序列呈稍低、等信号,其内夹杂可有斑片、云絮状高信号,增强扫描呈轻-中度强化;卵巢卵泡膜细胞瘤临床特征多伴发雌孕激素活跃引起的相关病症。结论卵巢卵泡膜细胞瘤体积较大、边界清,T_2WI压脂序列上以实性为主伴部分囊变者,可能要考虑到卵巢卵泡膜细胞瘤诊断,结合临床相关病史,有助于该病的诊断以减少误诊。Objective To analyze the MRI features of ovarian thecoma. Methods The MRI of 14 patients with histologically confirmed ovarian thecomas was analyzed retrospectively and correlated with the clinical and pathologic features. Results The tumors presented as solid masses with T2 iso-or hypointensities as well as patchy hyperintense cystic areas. All tumors exhibited mild contrast enhancement. Increased estrogen and progesterone were found in all patients. Conclusions MRI manifestations of ovarian theeomas are variable and nonspeeific. A large, well-defined, mildly enhancing solid mass with T2 iso-or hyporintensity and cystic areas in the clinical setting of elevated sex hormones may suggest the diagnosis of ovarian thecoma.
