Mycotic Aneurysm of the Posterior Cerebral Artery

Abstract

A 31-year-old male patient who presented with headache, chest uneasiness, and blurring of vision in the left eye. A computed tomographic scan revealed a large hematoma in the left occipital lobe. Echocardiogram showed mitral valve vegetations. Digital subtraction angiography revealed a fusiform aneurysm of the distal posterior cerebral artery. Subsequent angiogram revealed enlargement of the aneurysm. The patient was subjected to craniotomy with evacuation of the hematoma and excision of the aneurysm. Histopathology confirmed it to be a mycotic aneurysm.
