title: Cerebral astroblastoma resembling an extra-axial neoplasm.
abstract: A case of a cerebral astroblastoma is described in which MR imaging findings suggested the diagnosis of an extra-axial neoplasm. The lesion was proven to be intracerebral both surgically and histopathologically. Calvarial erosion, and buckling of the cerebral cortex by a peripherally located well circumscribed, highly enhancing mass, were the main MR findings leading to an errogenous preoperative diagnosis of an extra-axial mass. An astroblastoma should be included to the differential diagnosis of a superficially located tumor presenting with the findings of an extra-axial mass, especially in a young patient.
