Abstract:
Four children, with histopathologically confirmed posterior fossa primitive neuroectoderrnal tumors, were examined by plain radiography, computed tomography (CT) and cerebral angiography. The homogeneously well enhanced solid mass in the midline of the posterior fossa and hydrocephalus of various degree were seen on all CT scans. One case had calcifications and another case had low density areas in the tumor mass. Three cerebral angiograms showed vascular displacement without tumor vascularities. Unfortunately, these CT and angiography findings are and other tumors. when a well enhanced solid mass in the midline posterior fossa is seen on CT scan in children.
