A Case of Atraumatic Angular Vein Thrombosis

Abstract

Angular vein thrombosis is a rare vascular disorder marked by the occlusion of the angular vein by a blood clot. We report the case of a 70-year-old woman who presented with a visible bulge near her left nasojugal groove for one week and had no other associated symptoms or pertinent medical history. Subsequent maxillofacial CT scans with contrast revealed left angular vein thrombosis with dilation of the facial vein inferiorly. Despite its rarity, angular vein thrombosis poses a diagnostic challenge due to overlapping symptoms with other vascular and nonvascular pathologies. This case highlights the importance of early identification to prevent complications such as facial venous circulation obstruction and clot migration to the cavernous sinus.
