Ruptured Intracranial Bacterial Aneurysms: Report of Two Cases

ABSTRACT

Two Cases of ruptured bacterial aneurysms involving the distal branches of the middle cerebral artery associated with an intracerebral hematoma are reported. Both patients presented with a medical history of valvular heart disease and subacute bacterial endocarditis. The mortality of ruptured intracranial bacterial aneurysms has been reported to be very. High and a proper treatment strategy for such aneurysms still remains controversial. Most authors have recommended aggressive antimicrobial therapy, serial antiographic follow-up studies, and surgery for aneurysm's that do not resolve or enlarge even after medical treatment. Both of the reported patients were treated with antibiotics and underwent surgical evacuation for huge-sized intracerebral hematomas, and in one patient, the aneurysm was completely resected.
