摘　　要：目的探讨神经节细胞瘤的CT特征。方法回顾性分析12例经病理证实的神经节细胞瘤的CT表现。结果12例神经节细胞瘤位于肾上腺8例,腹膜后3例,后纵隔1例。CT平扫11例表现为边缘清楚均一低密度或等密度的卵圆形肿块,1例为混杂囊实性密度。1例可以看见小点状钙化。在增强CT上,肿瘤无强化2例,轻度强化4例,中度强化3例,高度强化3例。有5例表现为轻度延时强化,4例表现为明显延时强化,另3例无延时强化。结论神经节细胞瘤较为典型的CT表现为平扫低密度,增强扫描动脉期强化较弱,可见进行性的延迟强化。Objective To investigate CT characteristics of ganglioneuroma. Methods CT findings in 12 patients with ganglioneuroma proved histopathologically were retrospectively analyzed. Results The lesions localized in the adrenal gland in 8,the retroperitoneum in 3, the posterior mediastinum in 1. eleven lesions appeared as homogeneous hypo - or isodense oval masses with well delineated margins and 1 was cysto -solid on plain CT scans. The calcifications were seen inside one tumor. On enhanced CT scans ,the lesions were mild enhancement in 4, moderate enhancement in 3, significant enhancement in 3 and no enhancement in 2. Mild delayed enhancement in 5 cases, moderate delayed enhancement in 4 cases and no delayed enhancement in 3 cases were showed. Conclusion Typical ganglioneuroma shows low intensity, mild or moderate enhancement and delayed enhancement.
