Radiological Finding Exegetical to a Rare Arteriovenous Malformation: A Case Report

Abstract

Arteriovenous malformations (AVMs) are significant vascular lesions that can appear in infancy and are rather uncommon in the craniofacial region. AVM is a vascular anatomical anomaly that can be deadly or incapacitating since it occurs where the venous and artery systems join. The main causes of AVMs are infections, trauma, secondary thrombosis, puberty, and pregnancy. The skeletal muscles are rarely affected by intramuscular vascular malformations (IMVMs), which account for less than 1% of all head and neck tumors. The most often affected muscle is the masseter, which accounts for around 5% of the IMVM in the head and neck. About 40% of the venous anomalies in the head and neck region are associated with phleboliths. Advanced diagnostic aids like Ultrasonography with dopplers, Computed Tomography, and Cone Beam Computed Tomography give us a 3-Dimensional perspective that is more helpful in diagnosing such rare presentations. In this case report, many cutting-edge digital modalities that have helped to diagnose a venous malformation associated with multiple phleboliths in the masseter region of a 16 year old female are highlighted.
