目的 分析 7例罕见肾上腺间质肿瘤的CT表现。方法 对 7例经手术和病理证实的肾上腺间质肿瘤的CT表现进行回顾性分析 ,其中肾上腺囊肿、肾上腺脂肪瘤各 2例 ,肾上腺神经纤维瘤、神经鞘瘤及间叶瘤各 1例。结果 肾上腺囊肿及脂肪瘤分别为水和脂肪密度 ,CT特征明显 ;神经纤维瘤及神经鞘瘤为较低密度肿块 ,增强后不强化 ,神经鞘瘤密度不均匀 ,可见囊变 ;间叶瘤为较大的等密度肿块 ,增强后呈轻～中度强化。结论 肾上腺囊肿和脂肪瘤CT可明确诊断 ;神经纤维瘤、神经鞘瘤及间叶瘤CT特征不明显 ,较难或不能与腺瘤和嗜铬细胞瘤鉴别 ,确诊需依赖组织学检查
Objective To analyze CT findings of 7 cases of adrenal stromal tumors. Methods The CT findings of 7 adrenal stromal tumors confirmed by surgery and pathology were retrospectively analyzed. Among them, 2 cases were adrenal cyst, adrenal lipoma, adrenal neurofibroma, schwannoma and mesothelioma respectively. Results Adrenal cyst and lipoma were water and fat density, CT features were obvious; neurofibromatosis and schwannoma for the lower density mass, enhanced after not strengthen, schwannoma density is not uniform, visible cystic change; mesothelioma is Larger isodense mass showed a mild to moderate enhancement. Conclusion Adrenal cyst and lipoma CT can be clearly diagnosed; neurofibromatosis, schwannoma and mesothelioma CT features is not obvious, more difficult or can not distinguish with adenoma and pheochromocytoma, the diagnosis depends on histological examination
