摘要：This report details the CT and MR imaging findings of a primary orbital Ewing's sarcoma case involving the middle cranial fossa in a 13-year old boy.CT showed an ill-circumscribed homogeneous soft-tissue density mass with needle-like bone reaction.On MRI,the mass showed homogeneous iso-intensity on T1WI,heterogeneous hyperintensity on T2WI,and marked homogeneous enhancement.Meanwhile,the mass was hyper-intense on DWI,and ADC value was 575× l0-6 mm2/s.The mass showed as high rCBV and rCBF,prolonged MTT based on DCSPWI,and wash-out pattern of TIC derived from the DCE-MRI.Our case suggests that functional MRI modalities,including DWI,DSC-PWI or DCE-MR,could provide additional information for differential diagnoses.Both CT and MRI should be performed and comprehensively analyzed for limiting differential diagnoses,determining lesion extension and facilitating operative approach.
