A Rare Case of Adrenal Arterio-Venous Malformation (AVM): A Case Report

Abstract

Arterio-venous malformations (AVMs) are congenital vascular lesions in which dysplastic arteries are connected to the veins without an intervening capillary bed. High arterial flow directly into venous structures can lead to disruption of the venous walls and ultimately cause hemorrhage. These malformations can be found in the muscles, subcutaneous fat, bone and mainly in the central nervous system. We describe a rare case of adrenal AVM in a 6year-old boy who arrives at the emergency room of the "Santobono" hospital.
