 We will be using case material from our Imaging Center to illustrate the imaging findings and pathological manifestations. We have collected imaging and pathological data on sixteen patients with pPNET/EWS. The purpose of this exhibit is:  To review the radiological and clinicopathological findings of the peripheral primitive neuroectodermal tumor (pPNET)/Ewing sarcoma (EWS).  To discuss the radiological and pathological correlation of pPNET / EWS.  To explain the utility of CT/MRI particularly contrast enhanced CT/MRI in the diagnosis of pPNET / EWS.

 Clinicopathology of pPNET / EWS  Review of imaging findings of pPNET / EWS     –Conventional CT and MRI     –Contrast enhanced CT and MRI  Sample cases and mimics  Summary pPNETs showed various radiological appearances. Tumors arising from different sites had different signs correspondingly. MRI could reveal more precisely the size and shape of tumor and its local invasion than CT and X-ray. The correct diagnosis depended on the inspection of pathology and immunohistochemistry.
