Abstract

Meningiomas are common intracranial tumours which rarely extend to extra cranial sites. Here, the authors report a rare case of an intracranial meningioma with extracranial spread into the subcutaneous tissues of the scalp, with a brief overview of the literature. An 82-year-old man presented following a fall. At the time of assessment, it was noted that he had a large deformity over the frontal area of his scalp. It was unclear as to the duration of this deformity. Following an inconclusive CT head he underwent a MRI head which revealed an intracranial mass which extended across the frontal lobes. The mass permeated through the skull and extended through to the scalp. He underwent a biopsy of the extracranial component. The histology of which suggested a benign meningioma with low mitotic activity.
