MSCT angiography diagnosis of thrombosis in external jugular venous aneurysm: case report and review of literature.

True venous aneurysms are rarely-observed causes of neck swelling reported in children. We describe a 59-year-old female with a history of left-sided neck swelling due to external jugular venous aneurysm diagnosed by MSCT angiography. Thrombosis in external jugular venous aneurysm as in this case is extremely rare. Incidental note was made of the coexistent right internal jugular phlebectasia. A brief review of literature of this entity has been discussed.
