目的分析后腹膜神经节细胞瘤的CT和MR表现。方法回顾性分析1例经手术证实的后腹膜神经节细胞瘤患者的肿瘤的CT和MR表现,并作文献复习。结果肿块边界清楚,CT平扫表现为均一的低密度,并且其中可以看见小点状钙化。增强扫描延迟期可见进行性不均一的强化。MRT2WI上呈不均一的高信号,T1WI上表现为低信号。增强MR扫描呈轻度强化。结论在后腹膜肿瘤的鉴别诊断中神经节细胞瘤是一种较少见的肿瘤,它常常表现为边界清的肿块,并且具有包绕周围大血管生长的倾向。CT平扫为低密度,增强扫描在CT和MR上均表现为延迟期进行性的增强。
Objective To analyze CT and MR findings of retroperitoneal ganglioneuromas. Methods A retrospective analysis was performed on the CT and MR findings of 1 patient with retroperitoneal ganglioneuroma confirmed by surgery. Results The mass boundary was clear. The CT scan showed uniform low density, and dotted calcification was seen. Increased scanning delay can be seen progressive heterogeneity enhancement. MRT2WI was uneven on the high signal, T1WI showed low signal. Enhanced MR scanning showed a slight enhancement. Conclusions Ganglioneuroma is a rare tumor in the differential diagnosis of retroperitoneal tumors. It often presents as a clear boundary mass with a tendency to envelop surrounding large blood vessels. CT scan for the low density, enhanced scan in the CT and MR showed a progressive enhancement of the delay.
