title: Carcinoma metastasis to meningioma.
abstract: A metastasis from a carcinoma of the lung to an intracranial meningioma is described. This event is being reported more frequently, with most cases being seen since 1970. In patients with carcinoma, biopsies of intracranial tumours should include hyper- or hypodense regions in the tumour seen on CT.
