Glioblastoma Multiforme Associated with Arteriovenous Malformation: A Case Report and Literature Review

Although microvascular proliferation can be observed in glioblastoma, obvious vascularity coupled with coexisting cerebral arteriovenous malformation (AVM) is extremely rare. This report is of a rare case of glioblastoma, coexisting with a cerebral AVM. A 20-year-old male presented with progressive right hemiparesis within 1 month. Cranial magnetic resonance imaging revealed a large bleeding tumor with surrounding dilated vessels. Cerebral angiography demonstrated a left frontal AVM with a 1.2 cm nidus. The patient underwent preoperative embolization and radical resection. The coincidence of glioma and AVM was a rare association. However, the concept of hypervascular glioblastoma has been used in different states from different literature reviews; therefore, the role of proangiogenic factors should be addressed.
