Imaging Findings of an Aggressive Multicompartmental Venous Vascular Malformation of the Skull Base

Abstract

Primary vascular lesions are classified as vascular neoplasms and vascular malformations (VMs). Venous VM is the most frequent type of VMs with a prevalence of approximately 1% and is the most common venous anomaly in the head and neck region after hemangioma, but is rarely encountered in the skull base. An expansile growth pattern is noted with permeation into the tissue spaces by adjacent structure invasion, thus presenting with multicompartmental occupation, as in our case. Presented herein is a case of a 12-year-old female patient complaining of left orbital swelling with an aggressive venous VM of the skull base predominantly occupying the left infratemporal fossa extending into various other compartments.
