Spontaneous Ruptured Brain Arteriovenous Malformation In Adolescent Patient: Case Report

Introduction: Brain arteriovenous malformations (bAVMs) are one of the most common causes of intracranial hemorrhage in the adolescent. AVMs are relatively rare as congenital intracranial abnormalities but these lesions are becoming frequently reported. AVMs generally has no any symptoms and only recognized after intracranial or subarachnoid hemorrhage occurs. This disease usually gives symptoms of headaches and seizures without cause. However, along with the development of medical technology, arteriovenous malformation lesions are common. Case report: This 24 year old woman in unconscious with right hemiparesis and atypical chronic progressive headache with vas 8-9, without aura. Previously the patient had a seizure with a duration of 5 minutes, rigid all over body. The patient had no prior history of trauma, infection, hypertension, diabetes or stroke. GCS E2M5Vaphasia with motoric aphasia, motoric and sensory deficits in the form of right hemiparesis, paresis of N. VII, increased physiological reflexes, and positive Babinsky reflex. CT-Scan Angiography imaging of the head showed intraparenchymal bleeding in the left temporoparietal lobe with perifocal edema, AVM in the left temporalis region with a nidus with a feeding artery from the left MCA and a draining vein from the left transverse sinus. The patient was referred for further vascular intervention. Discuss: AVMs was previously considered a congenital malformation with risk of bleeding in anomalous tissue or nidus occurring within the brain parenchyma. Rupture of the artery and discharge into the subarachnoid space causes a sudden increase in ICP, cerebral vascular vasospasm resulting in global and focal brain dysfunction. In addition, with the increasing use of non-invasive intracranial imaging, AVMs can be detected directly.
