Abstract
Jugular venous pseudoaneurysm represents an exceedingly rare vascular abnormality and may present as an atraumatic neck mass. We report the clinical presentation, imaging findings, operative management under local anesthesia, anticoagulation strategy, and follow-up of a patient with a thrombosed jugular venous pseudoaneurysm after exclusion of common secondary causes. Duplex ultrasonography and CT angiography confirmed the diagnosis and guided surgical planning; complete excision with preservation of venous continuity was performed without perioperative complications, and follow-up duplex at 3 months demonstrated no recurrence. A jugular venous pseudoaneurysm should be considered in the differential diagnosis of atraumatic neck swelling; management should be individualized based on symptoms, thrombus burden, and imaging findings, with surgery favored for symptomatic or thrombosed lesions.
