Management of an external jugular vein aneurysm in a young patient.

External jugular vein aneurysm (EJVA) is a rare clinical entity. A 23-year-old man presented with a spontaneous unilateral cervical swelling. Physical examination revealed a soft, nonpulsatile mass at the left supraclavicular region. Color duplex ultrasound combined with computed tomography confirmed the diagnosis of an EJVA. A surgical excision was accomplished without any complications during the early follow-up. EJVA mandates a high index of suspicion in the differential diagnosis of a neck mass. The open surgical approach seems to be a safe and effective therapeutic strategy.
