Abstract
The attenuation profiles before and after contrast enhancement were examined in 18 infants and children with posterior fossa tumors: eight cerebellar astrocytomas, six medulloblastomas, and four brainstem tumors. The astrocytomas, with one exception, had characteristic patterns, and all could be distinguished from the medulloblastomas, which have a distinct pattern of their own. The brainstem tumors had varying appearances, and were entirely low-attenuating, high-attenuating or had a ring shadow after enhancement. The nature of a posterior fossa tumor in a pediatric patient can usually be predicted fairly satisfactorily from a computed tomogram.
