摘　　要：目的:探讨卵巢卵泡膜细胞瘤的CT表现及其诊断价值。方法:回顾性分析30例(32个肿瘤)有完整临床和CT资料并经病理证实为卵巢卵泡膜细胞瘤患者的CT表现,并结合临床及病理资料进行对照分析。结果:肿瘤形态规则22例(73.3%),边缘光滑29例(96.7%)。肿瘤为实性型23例(76.6%),囊实性5例(16.7%),囊性型2例(6.7%),实性肿瘤中肿瘤越大低密度区越多。CT平扫示肿瘤密度低,肿瘤实性成分CT值(38.51±10.15)HU,低于肌肉(42.97±9.85)HU;增强扫描示肿瘤呈轻度强化,CT值[(44.21±20.33)HU]低于肌肉[(55.93±12.89)HU]。合并腹部和盆腔淋巴结肿大2例(6.7%),肠系膜增厚5例(20%),无腹水9例(30.0%)、少量腹水19例(63.4%)。结论:卵巢卵泡膜细胞瘤的CT表现有一定特征性,CT是诊断本病的有价值的诊断方法。Objective：To analyze the computed tomographic（CT）features of ovarian fibrothecoma and its diagnostic value.Methods：Thirty cases with 32 lesions of ovarian fibrothecoma proven pathologically including complete clinical informations and CT images from 1999 to 2009 were analyzed retrospectively.Results：The outcoming showed the maximum diameter of the tumor was（9.78±4.17）cm with regular shape in 22 cases（73.3%）,smooth border in 29 cases（96.7%）.The tumors were solid in 23 cases（76.6%）,mixed in 5 cases（16.7%）and cystic in 2 cases（6.7%）;and furthermove with more low density areas within larger solid tumors.On plain CT the tumors showed hypo-density with CT attenuation of solid partion as（38.51±10.15）HU,lower than that of surrounding muscle（42.97±9.85）HU.Tumors were slighty enhancemend with CT attenuation of（44.21±20.33）HU which were lower than those of the correlation muscle（55.93±12.89）HU.There were 2 cases of abdominal and pelvic lymph nodes enlargement（6.7%）,5 cases of mesenteric thickening（20%）.No ascites was observed in 9 cases（30%）and mininal ascites in 19（63.4%）.Conclusion：The ovarian fibrothecomas posses specific CT characteristic manifestations and thus CT provides as a valuable diagnostic measure and should be the first choice of managment.
