摘要: Rhabdoid tumors of the central nervous system are rare malignancies. Primary atypical teratoid/rhabdoid (ATT/RhTs) mostly occur during early childhood and almost invariably fatal. These show similar histological radiological features to primitive neuroectodermal tumormedulloblastoma (PNET-MB) but have different biological behaviors. We report a case primary intracranial ATT/RhT in posterior cranial fossa child. Preoperative diagnosis was PNET-MB, pathological is ATT/ RhT. The involved 16-month-old baby boy who presented with severe headache, vomiting, gait disturbance. He treated by surgical resection, chemotherapy, radiotherapy.
