title: Extensive and dense calcification in the core of a ventrally exophytic brainstem glioma.
abstract: The first case of a ventrally exophytic pontine glioma with extensive and dense calcification is reported. A 10-year-old boy presented with a generalized seizure. The skull radiogram and CT scan showed a dense area of calcification, revealed by MRI as the core of a ventrally exophytic tumor. The pathologic diagnosis was fibrillary astrocytoma.
