Arteriovenous malformation (AVM) is a defect of the circulatory system consisting of an abnormal connection between the arterial system, which normally has a higher intravascular pressure and the lower pressure venous pathways.Arteriovenous malformation presents later in childhood or, more frequently, in adults in the second to third decade of life. These abnormal communications are divided into two types, plexiform and fistulous.Cerebral arterio-venous malformations are one of the challenges for neuro surgeons. Medial temporal AVM are a special group in the medial hemispheric AVM and may be successfully resected using a direct microsurgical approach with limited morbidity and excellent prognosis for recovery.
