目的:分析卵巢卵泡膜细胞瘤的CT表现特点,以提高对此病的认识和诊断水平。方法:回顾性分析12例经手术病理证实的卵巢卵泡膜细胞瘤患者的临床资料和CT表现。CT表现从部位、大小、形态及边界平扫密度特征及强化程度,病灶有无囊变及腹水等进行分析。密度特征以子宫肌层密度作为参照。结果:12例患者临床上发病年龄为23～66岁,平均38岁。其中合并子宫肌瘤2例,合并子宫腺肌症1例,合并宫颈癌1例。12例肿瘤均为单侧。大部分肿块形态以圆形或卵圆形为主。肿块小者约1.5cm×2.0cm,大者约5.5cm×7.0cm,平均约2.8cm×3.0cm。CT平扫7例为实性肿块,4例为囊实性,1例为完全囊性。无腹水8例,少量腹水4例。增强扫描实性部分动脉期强化不明显,实质期不均性轻度强化为主要表现,囊性部分未见强化。结论:卵泡膜细胞瘤CT表现的良性形态特征,特别是其乏血供性轻度强化特征,有助于对该肿瘤的诊断及鉴别诊断。
Objective: To analyze the CT features of ovarian follicular cell tumor in order to improve the understanding and diagnosis of this disease. Methods: The clinical data and CT findings of 12 patients with OCC confirmed by surgery and pathology were analyzed retrospectively. CT performance from the location, size, shape and boundary density characteristics and degree of enhancement, cystic degeneration and ascites, etc. were analyzed. Density characteristics of myometrial density as a reference. Results: The clinical onset age of 12 patients was 23 to 66 years old, with an average of 38 years. Including uterine fibroids in 2 cases, 1 case of adenomyosis combined with cervical cancer in 1 case. All 12 tumors were unilateral. Most lumps are round or oval in shape. Small tumor about 1.5cm × 2.0cm, the largest about 5.5cm × 7.0cm, an average of about 2.8cm × 3.0cm. CT scan in 7 cases of solid mass, 4 cases of cystic solid, 1 case of complete cystic. No ascites in 8 cases, a small amount of ascites in 4 cases. Enhancement of the real part of the enhanced solidus arterial phase was not obvious, the substantive period of mild enhancement as the main performance, the cystic part of no strengthening. Conclusion: The positive morphological features of CT manifestations of SCC, especially the mild enhancement of SCC, are helpful to the diagnosis and differential diagnosis of this kind of tumor.
