摘要:
目的总结后纵隔神经节细胞瘤的CT和MRI表现，提高对其认识。 方法回顾18例经病理证实的后纵隔神经节细胞瘤患者的影像学资料（CT或MRI），与病理对照，对其影像表现进行分析、总结。 结果本组11例发生于20岁以下，女性12例；病灶体积常较大，12例最大径线大于3 cm；CT值约20~40 Hu，大部分密度均匀；T1WI信号较低，T2WI呈高信号，2例其内可见低信号；增强扫描早期无强化，延迟期轻度强化。 结论后纵隔神经节细胞瘤具有一定的影像学特点，通过影像学方法能做出较准确的诊断。 Abstract:ObjectiveTo summarize the CT and MRI features of posterior mediastinal ganglioneuroma. MethodsImaging data (CT or MRI) of 18 posterior mediastinal ganglioneuroma patients were retrospectively reviewed, and the imaging features were summarized in comparison with pathology. ResultsEleven cases under 20 years of age were occurred, with 12 female. The lesion size were large, the largest diameter of 12 cases were greater than 3 cm. CT value was about 20-40 Hu, and most tumors were homogeneous in density with low signal intensity on T1WI, high signal intensity on T2WI.Two cases of tumors showed low signal with no enhancement at early stage and slight enhancement in delayed phase. ConclusionThe posterior mediastinal ganglioneuroma has certain imaging features, and it can be diagnosed accurately by imaging method. -
图 1 F-16Y右后上纵膈神经节细胞瘤
A: 平扫病灶呈类圆形低密度影（CT值约24 Hu）,边界清楚,密度均匀,低于同层肌肉密度; B: 增强扫描延迟期病灶轻度强化（CT值约31 Hu）
图 2 F-49Y左后上纵膈神经节细胞瘤
A,B: CT平扫是病灶边界清楚,密度均匀,呈稍低密度（CT值约21 Hu其内可见点状钙化灶）; C: 增强扫描是病灶轻度强化 （CT值约25 Hu）,冠状位重建示病灶纵轴长度大于其他径线.
