External jugular venous aneurysm: A rare case report

Abstract

Venous aneurysms of the external jugular vein are rare vascular anomalies due to the low pressure in the venous circulation i.e. the superior vena cava. A review of the literature reveals that external jugular vein aneurysms are reported rarely but the exact incidence of such aneurysms is not known. The presentation of external jugular vein aneurysms can vary widely but generally, they present as a soft cervical mass which gradually increases in size. These aneurysms pose a diagnostic and management challenge for the clinician as their clinical spectrum ranges from being asymptomatic, to cosmetic concerns or they can potentially cause thrombosis, embolism, or thrombophlebitis. Diagnosis is confirmed via Color Doppler ultrasound and computerized tomogram angiography. We present the clinical features and diagnosis of a saccular external jugular vein pseudoaneurysm in a 58-year-old female, which was most likely to be congenital and was diagnosed using computerized tomogram angiography.
