目的探讨节细胞神经瘤的CT、MR表现特征,提高诊断水平。方法回顾性分析19例经手术病理证实的节细胞神经瘤的CT表现,并作文献复习。结果节细胞神经瘤的CT、MR表现有以下特点:肿块边界清晰,多呈卵圆形,密度较均匀,平扫密度低于竖脊肌,常见小点状钙化,偶有囊变,增强扫描呈轻、中度不均匀强化,强化程度弱于竖脊肌。结论节细胞神经瘤的CT、MR表现具有一定特征性,认识该CT、MR表现特征有助于与其他肿瘤鉴别。
Objective To investigate the CT and MR features of ganglioneuroma and to improve the diagnosis. Methods CT findings of 19 cases of ganglioneuromas confirmed by surgery and pathology were retrospectively reviewed and reviewed in the literature. RESULTS: The CT and MR features of ganglioneuroma showed the following characteristics: clear mass margins, mostly ovoid, denser density, less flattening density than erector spinae, common punctate calcification, occasional cystic degeneration, and enhanced scanning. It was light and moderately inhomogeneous and strengthened to a lesser extent than erector spinae. Conclusion CT and MR features of ganglioneuroboma have certain characteristics. It is helpful to distinguish the features of CT and MR from other tumors.
