目的 探讨肾上腺少见和罕见肿瘤的CT表现特征和鉴别诊断。方法 对 9例经手术和病理证实的肾上腺少见肿瘤之CT表现进行回顾性分析 ,其中肾上腺节细胞神经瘤 3例 ,肾上腺神经母细胞瘤 2例 ,肾上腺囊肿、肾上腺脂肪瘤、肾上腺神经纤维瘤及肾上腺间叶瘤各 1例。结果 肾上腺囊肿、神经母细胞瘤和肾上腺脂肪瘤各有其CT表现 ;肾上腺节细胞神经瘤 ,神经纤维瘤及间叶瘤CT平扫均为较大体积的较低密度或等密度肿块 ,增强后节细胞神经瘤及神经纤维瘤不强化 ,间叶瘤轻到中度强化。结论 肾上腺囊肿、神经母细胞瘤和脂肪瘤CT可明确诊断 ;肾上腺节细胞神经瘤 ,神经纤维瘤及间叶瘤CT特征明显 ,较难或不能与腺瘤或嗜铬细胞瘤鉴别 ,确诊仍需结合临床及组织学检查
Objective To investigate the CT features and differential diagnosis of rare and rare adrenal tumors. Methods Nine cases of benign adrenal tumors confirmed by surgery and pathology were retrospectively analyzed. There were 3 adrenal ganglioneuroma, 2 adrenal neuroblastoma, adrenal cyst, adrenal lipoma, adrenal neurofibroma, Adrenal mesothelioma in 1 case. Results Adrenal cyst, neuroblastoma and adrenal lipoma had their own CT appearances. The adrenal ganglioneuroma, neurofibromatosis and mesothelioma CT scan were larger volume of lower density or isodense mass, Cell neuroma and neurofibromatosis is not enhanced, mesothelioma mild to moderate enhancement. Conclusion Adrenal cyst, neuroblastoma and lipoma CT can be clearly diagnosed; adrenal ganglioneuroma, neurofibromatosis and mesothelioma CT features more difficult or not with adenoma or pheochromocytoma identification, the diagnosis is still required Combined with clinical and histological examination
