Cavernous Sinus Vascular Venous Malformation.

ABSTRACT

Vascular venous malformations of the cavernous sinus have multiple imaging features that can be used to distinguish them from other entities in the region. Accurate identification of these lesions is essential Vascular venous malformation lesions carry considerable risk of intraoperative hemorrhage, so preoperative recognition of vascular venous malformations can greatly impact the treatment strategies used. Nevertheless, because of their scarcity, many radiologists are unfamiliar with the radiologic and clinical features of cavernous sinus vascular venous malformations. This article will describe a case of an asymptomatic vascular venous malformation; outline its imaging, clinical, and pathologic features; and review the relevant literature regarding this diagnosis.
