title: Thrombosed Aneurysm of the External Jugular Vein: A Rare Cause of Cervical Mass.
abstract: BACKGROUND
  External jugular vein aneurysm is a rare condition with few cases described in the literature. Complications include thrombus formation, thrombophlebitis, pulmonary embolism, rupture, and cosmetic complaint.
  
  
  RESULTS
  The authors present a clinical case and treatment of thrombosed aneurysm of the external jugular vein in a 47-year-old man.
  
  
  CONCLUSIONS
  Despite its rarity, external jugular vein aneurysm should be remembered in the differential diagnosis of a cervical mass. Surgical excision is indicated in symptomatic aneurysms and for aesthetic reasons. Excision eliminates the risk of complications and allows for histopathologic diagnosis.
