目的探讨神经节瘤的CT影像特征及其诊断。方法回顾性分析7例经手术病理证实为神经节瘤的CT影像表现,并结合相关文献复习,讨论其影像特征、诊断及鉴别诊断。结果肿瘤位于后纵隔1例,位于肾上腺区2例,位于腹膜后4例,均表现为椭圆形或分叶状较均匀等密度实性肿块,增强后轻度或未见明显强化,边界清晰,有完整包膜,部分病灶内可见点状钙化,对周围血管呈包绕,压迫改变,并未见浸润。结论神经节瘤具有一定特征性影像表现,可在术前作出正确的定位及较准确的定性诊断。
Objective To investigate the features and diagnosis of CT images of ganglioma. Methods Retrospective analysis of 7 cases of pathologically confirmed ganglion tumor CT image performance, combined with relevant literature review, discuss its imaging features, diagnosis and differential diagnosis. Results The tumor was located in the posterior mediastinum in 1 case, in the adrenal area in 2 cases and in the retroperitoneum in 4 cases, which showed oval or lobulated more uniform density of solid tumors with mild or no enhancement after enhancement with clear boundary, A complete capsule, some lesions visible dot-like calcification, surrounded by the surrounding blood vessels, oppression change, and no infiltration. Conclusion The ganglioneuroma has certain characteristic imaging manifestations, which can make correct positioning and accurate diagnosis before operation.
