title: Aneurysmal bone cysts in the cranial vault and base of skull.
abstract: Three cases of aneurysmal bone cyst of the skull are reported. The localization in the base of the skull (two cases) is extremely rare and simulates a space-occupying intracerebral lesion. The clinical and microscopic findings, and their significance for the differential diagnosis from malignant brain tumors, are described.
