Abstract
Radiographic findings are reviewed in 31 children with primitive neural ectodermal tumors seen at the Hospital for Sick Children from 1962-1983. Seventeen children were initially evaluated with computed tomography (CT). Of these, 10 had both CT studies on angiography. The tumors were large, irregular, typically iso- to hyper-dense, and showed dense, heterogeneous contrast enhancement. Cysts were present in 65% and calcifications in 71% of the cases. The angiographic findings were usually found in the cerebral hemisphere, particulary the frontal lobes, 2 cases are included of tumors arising elsewhere: 1 in the pineal and 1 in the suprasellar region. Epidemiologic data are reviewed.
