Abstract

Intra-tumoral infarction is a rare complication in patients with meningioma. We report a case of a 36-year-old woman with a diagnosis of osseous cranial frontal and parietal dysplasia associated with multiple extra-axial lesions suggestive of meningiomas, that acutely developed headache, right-sided weakness, obnubilation and motor aphasia with progressive worsening. Head Computed Tomography and brain Magnetic Resonance Imaging were suggestive of intra-tumoral meningioma infarction, with a central area of necrotic-core and peripherical concentric contrast enhancement as well as signs of intracranial hypertension. The patient was submitted to surgery to remove the lesion, confirming the suspected diagnosis by histopathology analysis.
