Objective To explore the MRI features of primitive neuroectodermal tumors of central nervous system (CNS PNET) in order to improve the diagnosis of MRI in CNS PNET. Methods MRI imaging data of twelve cases with CNSPNET which confirmed by pathology were analyzed retrospectively. Results The 12 cases both underwent MRI plain scan and enhancement, 6 males and 6 females, aged from 1 to 48 years. The lesions were commonly found in the deep cerebral hemisphere, and more commenly in the temporal lobe, and one case spreaded in the cerebral. In the 12cases,7 were solid mass and 5 were cystic and solid mass, all the tumors had clear boundary as well as slight peritumoral edema. MRI images showed the solid part of the tumors to be middle or hypointense on T1 weighted images and hyperintense on T2 weighted images as well as hyperintense on DWI images. The cystic component to be hypointense on T1 weighted images and hyperintense on T2 weighted images. The enhancement images showed that 5 cases had a ring enhancement, and the other 7 cases had a heterogeneous enhancement. Conclusion Certain MRI features may suggest the diagnosis of CNS PENT, but still rely on pathological diagnosis.
