摘要: Objective To summarize the CT and MRI features of posterior mediastinal ganglioneuroma. Methods Imaging data(CT or MRI) of 18 posterior mediastinal ganglioneuroma patients were retrospectively reviewed, and the imaging featureswere summarized in comparison with pathology. Results Eleven 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 mosttumors were homogeneous in density with low signal intensity on T1WI, high signal intensity on T2WI.Two cases of tumorsshowed low signal with no enhancement at early stage and slight enhancement in delayed phase. Conclusion The posteriormediastinal ganglioneuroma has certain imaging features, and it can be diagnosed accurately by imaging method.
