摘要
目的:研究节细胞神经瘤的CT和MRI表现特点及其诊断价值。方法:对9例节细胞神经瘤行CT和MRI检查,9例均做CT平扫加增强,8例患者行MRI,其中4例MRI增强。所有病例均经手术病理证实。结果:6例位于腹膜后,2例位于纵隔,1例位于颈部,表现为椭圆形,所有病变边缘都非常锐利。在CT平扫上均为低至中等密度,在MRI上T1WI表现为低信号,T2WI上呈非均匀高信号;增强后表现为轻度或不均匀的中等度强化。结论:CT与MRI相结合能比较全面准确地反映节细胞神经瘤的特性,是目前诊断该病较为理想的方法。
Objective：To research the features and diagnostic value of CT and MRI of ganglioneuroma. Methods：CT and MRI examinations were performed in 9 cases, CT scanning was performed in all with both plain and enhanced scan. MRI was done in 8 cases,among which 4 cases were done with enhanced scan. All cases were confirmed by surgery and pathology. Results：6 masses were located in retroperitoneum region,2 in mediastinum and 1 in neck,which appeared elliptic with sharp edges. On CT plain scan the mass showed low or intermediate density. On MRI scan,the mass showed low signal on T1WI,inhomogeneous hyperintensity on T2WI and a slightly or inhomogeneously intermediate enhancement was seen on enhanced scan. Conclusion：The combination of CT and MRI can reflect features of ganglioneuroma thoroughly and precisely,and it is considered as an ideal method in diagnosing ganglioneuroma up to the present.
