摘要：

目的：探讨卵巢卵泡膜细胞瘤的MR特点，提高其诊断水平。方法：对经手术病理证实42例63个卵泡膜细胞瘤的MR资料、部分实验室检查进行分析。结果：42例63个病灶均呈实性或实性为主的肿块，T2 W呈明显低信号45个（79.6%），以低信号为主夹杂斑片状与云絮状略高信号18个（21.4%）；增强后肿块强化不明显14个，轻度强化35个，以轻度强化为主局部较明显强化14个；子宫内膜增厚6例（14.3%），腹水12例（28.6%），25例雌激素E2检查中有10例增高（40%）。结论：卵泡膜细胞瘤T2 W明显低信号及轻度强化方式为其特征性表现，子宫内膜增生及雌性激素E2增高有助于病灶的鉴别诊断。 Objective To explore the MRI features of ovarian thecoma for improving its diagnosis. Method In 42 patients with ovarian thecoma confirmed by surgery and pathology,MRI of 63 lesions and some laboratory data were analyzed. Results Solid or mostly solid mas-ses were showed in 63 lesions,T2 W image displayed low signal in 45 lesions( 79. 6%),low signals with patchy and cloud floccule in 18 (21. 4%). On the post-contrast dynamic phase,14 lesions showed no obvious enhancement,35 lesions displayed mild enhancement and 14 lesions showed mild enhancement with local hyperintense areas. Other findings included endometrial thickening in 6 patients,ascites in 12 patients. In 25 patients with measuring serum estradiol level,serum estradiol levels were elevated in 10 patients(40%). Conclusion -Hypointensity and mild enhancement on T2 W image are the features of the ovarian thecoma,Endometrial hyperplasia and high in serum es-tradiol level are helpful for the differential diagnosis of the ovarian lesions.
