摘　　要：目的 探讨卵巢卵泡膜细胞瘤的MRI表现特点.方法 回顾性分析经手术病理证实的21例卵巢卵泡膜细胞瘤的临床及MRI资料,重点分析MRI表现.结果 21例患者均为卵巢单发实性肿块,边界清晰,呈卵圆形或不规则分叶,直径3.0～16.0 cm,平均7.9 cm.MRI平扫病灶T1WI呈等或等低混杂信号,脂肪抑制T2WI病灶内部可见多发结节,结节呈低信号18例,极低信号3例,结节间夹杂散在条片状或裂隙状高信号影15例.增强扫描肿块渐进性轻度强化16例,中度强化5例.16例伴少量腹水,4例肿瘤蒂扭转.结论 卵巢卵泡膜细胞瘤MRI表现有一定特征,认识这些特征有助于该病的诊断及鉴别诊断.Objective To investigate the MRI manifestations features of ovarian thecoma. Methods Clinical and MRI data in 21 patients with ovarian theeoma proven were retrospectively analysed and focused on MR1 performance. Results The tumors in 21 ca ses all presented as a single solid mass with clear bounds,owd or irregular Iobulation. The diameter of the tumors was 3.0- 16.0 ern with mean 7.9 cm. The lesions were equal or mixed equal-lower signal intensity on T1WI,the visible nodules with low or marked signal intensity within lhe tumors in 18 eases and 3 cases were detected on fat suppressed T2WI,respectively,strip or fissured hyperin- lensilies inter nodules were seen in 15 cases. The lesions were progressive mild enhancement in 16 cases, moderate enhancement in 5 cases at contrast-enhanced scan. There were 16 cases with small amounts of aseites and 4 cases with tumor torsion. Conclusion Ovarian thecoma has certain charaeleristies on MR images, which is helpful for diagnosis and differential diagnosis of this tumor.
