Intraventricular hemorrhage secondary to AVM of the septum pellucidum

Abstract Arteriovenous malformations (AVMs) of the brain include congenital vascular lesions that represent about 2% of all hemorrhagic strokes. Despite the relative rarity of the disease (with a detection rate estimated at approximately 1/100.000 person-years), AVMs represent a significant neurological problem. Affected patients are mostly young and healthy. AVMs located in the medial region of the cerebral hemisphere and the limbic system comprise a special group with difficult access and consequent difficulties of resection. Furthermore, there is a high incidence of intracranial hemorrhage resulting from a complex venous drainage, sometimes directed to the superficial veins, but mostly to the deep venous system. The present case report illustrates a patient with an AVM centered on the septum pellucidum, whose initial clinical resulted from an intra-ventricular hemorrhage.
