Aneurysm occurring within a meningioma: case report

Aneurysms can be expected to be found in approximately 0.5% of patients with brain tumours; nevertheless, the real incidence is difficult to assess because angiography is now seldom performed for brain tumours. In the literature, 42 cases of meningioma associated with aneurysms are reported, but in none was the aneurysm intratumoural. We describe a case of intracranial meningioma with an intratumoural aneurysm in a 48-year-old woman.
