摘　　要：目的通过对卵巢卵泡膜细胞瘤的CT特点与病理结果对照分析,提高其认识和诊断水平。方法分析经手术病理证实的11例卵巢卵泡膜细胞瘤的CT特点与病理形态学表现进行对照。结果 11例均为单侧等密度肿块,4例密度均匀,7例密度不均匀。肿瘤实性部分CT平扫表现为稍低密度,发生坏死或囊变表现为片状更低密度,与术后病理所见坏死、囊性变基本一致。部分病灶内可出现纤维分隔,增强后病灶多为轻度均匀强化。8例CT上病灶实体均表现为稍高密度索条状影分割肿瘤,肿瘤细胞之间有较明显的胶原纤维。3例CT上病灶实体表现为均匀低密度,病理示胶原纤维相对较少,瘤细胞较多。结论 CT能很好显示卵泡膜细胞瘤的低密度及轻度强化,具有一定特征。能够较准确反映卵泡膜细胞瘤的病理特点。Objective To analyze and compare the CT appearances of ovarian thecoma with pathomorphologic findings in order to improve the knowledge of the desease.Methods CT findings in 11 patients with pathologically proved ovarian thecom were retrospectively analyzed and compared with findings of pathomorphology.Results All 11 cases showed a unilateral isodense mass with a homogeneous mass in 4 cases and a heterogeneous mass in 7 cases.Focal lesion displayed hypointensity in plain scan,lower density occurred when necrosis or cystic degeneration of the lesion existed,corresponded to pathomorphologic findings after surgery.Fibrous septation was detected in some lesions.After enhancement,most lesions showed mild enhancement.The focal lesion displayed linear opacity divided tumor in 8 cases,collagen hyperplastic was visible found between the oncocytes microscopically.The focal lesion displayed homogeneous hypointensity in 3 cases,corresponded to less amounts of collagen hyperplastic and more oncocytes.Conclusions Hypointensity and mild enhancement are the characteristics of ovarian thecom.The CT findings can reflect the features of the tumor correctly.
