A Pediatric Case of Diffuse Glioma Diagnosed at Autopsy

Sudden death from an undiagnosed primary intracranial neoplasm is extremely uncommon and even rarer in the pediatric population. Gliomatosis cerebri (GC) represents a growth pattern demonstrable by a variety of gliomas, predominating in adults. Herein we present a rare occurrence of diagnosis of a pediatric glioma with a GC pattern of infiltration at autopsy and compare the immunohistochemical results and molecular characteristics in this tumor to the small amount of published knowledge available about pediatric diffuse gliomas with widespread brain invasion.
