Dissecting aneurysm of the middle cerebral artery manifesting as subarachnoid hemorrhage and hemorrhagic infarctions - Case report

Abstract

A 46-year-old woman presented with a dissecting aneurysm of the right middle cerebral artery manifesting as subarachnoid hemorrhage followed by hemorrhagic infarctions. The aneurysm was clipped and wrapped. However, serial angiography showed progression of the lesion, which was probably responsible for the clinical course of this patient. Intracranial dissecting aneurysms are less common, and the natural history of these lesions is unclear. Conservative management might be preferable in this patient.
