肾上腺良性神经源性肿瘤的MSCT表现

MSCT finding of adrenal benign neurogenic tumors

目的:探讨肾上腺良性神经源性肿瘤的MSCT表现,以提高对此类病变的认识。方法:回顾性分析20例经手术及病理证实的肾上腺良性神经源性肿瘤的MSCT表现,其中嗜铬细胞瘤12例,节细胞神经瘤4例,神经纤维瘤3例,神经鞘瘤1例。结果:12例嗜铬细胞瘤均呈类圆形,边界清楚,其中6例伴有囊变,增强扫描动脉期均有明显强化;4例节细胞神经瘤形态不规则,呈嵌入式生长,密度均匀,增强扫描轻度强化;3例神经纤维瘤边界清楚,增强扫描具有延迟强化特点;1例神经鞘瘤增强扫描明显强化。结论:肾上腺良性神经源性肿瘤的MSCT表现具有一定的特征性,动态增强扫描对其诊断及鉴别诊断具有重要价值。

Objective：To investigate the MSCT finding of adrenal benign neurogenic tumors ,in order to improve the understand-ing of such lesions .Methods ：The MSCT finding of 20 cases with adrenal benign neurogenic tumors confirmed by operation and pathology were retrospectively analyzed ,which included 12 cases of pheochromocytoma ,4 cases of ganglioneuroma ,3 cases of neurofibroma ,1 cases of neurolemmoma .Results：12 cases of pheochromocytoma were round and regular margin ;6 cases with cystic change ,enhanced scan were significantly enhancement ;4 cases of ganglioneuroma were irregular ,embedding and homoge-neous density ,mild enhancement ;3 cases of neurofibroma were regular margin and delayed enhancement ;1 case of neurolem-moma was marked enhancement .Conclusion：There are some characteristics in adrenal benign neurogenic tumors with MSCT scanning ,and dynamic enhanced scan is very helpful for diagnosis and differential diagnosis .
