Symptomatic "Migraine with Aura" Due to Occipital Arteriovenous Malformation or "Headache Attributed to Arteriovenous Malformation (AVM)" Associated with Simple Partial Seizures in an Adolescent Patient - Case Presentation.

Arteriovenous malformations (AVMs) of the brain consist in a network of dilated vessels that form an abnormal communication between the arterial and venous system. The clinical presentation of AVM could be with acute haemorrhagic stroke, due to their rupture or with seizures or recurrent headache. We present the case of 12 year old male child who was admitted in our clinic for "migraine with visual aura"-like episodes with visual positive phenomena. On cerebral MRI (T1, contrast enhancement) we found a right occipital arterio-venous malformation of 2-3 cm in diameter. The patient was referred to gamma knife stereotactic radiosurgery treatment.
