To summarize the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of ovarian fibro the coma and to compare them with the pathological findings.
CT and MRI features of 25 patients with pathologically proved ovarian fibrothecoma were retrospectively analyzed.
Of these 25 patients,the tumors were single in 23 patients and bilateral in 2 patients. The tumors were round or oval in 16 cases and lobulated in 11 cases. CT plate scanning showed that both the solid masses and the solid components of the cystic and solid masses had slightly lower densities than that of the myometrium, and gradual and mild enhancement could be found in the arterial phase and delay phase after enhanced scan. MRI showed iso-low signal on T1-weighted imaging, slightly low or high signal on T2-weighted imaging of fat suppression sequences, slightly high signal on diffusion weighted imaging and the enhance characteristics as the well as CT after enhanced scan.Pelvic cavity effusion was seen in 3 cases.
Ovarian fibrothecoma have certain imaging characteristics,which are helpful to improve the diagnosis and differential diagnosis of this disease and lower the misdiagnosis rate before operation.
总结卵巢纤维卵泡膜瘤的计算机断层扫描（CT）和磁共振成像（MRI）特征，并与病理结果进行比较。
回顾性分析25例经病理证实的卵巢纤维卵泡膜瘤患者的CT和MRI特征。
这25例患者中，23例肿瘤为单侧，2例为双侧。16例肿瘤呈圆形或椭圆形，11例呈分叶状。CT平扫显示实性肿块及囊实性肿块的实性成分密度均略低于子宫肌层，增强扫描动脉期及延迟期可见渐进性轻度强化。MRI表现为T1加权像等低信号，脂肪抑制序列T2加权像呈略低或高信号，弥散加权成像呈略高信号，增强扫描后强化特点与CT相同。3例可见盆腔积液。
卵巢纤维卵泡膜瘤具有一定的影像学特征，有助于提高该病的诊断及鉴别诊断能力，降低术前误诊率。
