Brain tumors in infants less than a year of age.

A retrospective examination of brain tumors in infants less than a year of age was undertaken by reviewing their charts and CT scans. In contradistinction to brain tumors found in older children, most tumors were supratentorial in location. The most common histologic types included: astrocytoma, ganglioglioma and primative neuroectodermal tumors. Apart from their larger size at the time of presentation, these tumors were radiologically and pathologically similar to analogous tumors found in adults.
