Unilateral internal jugular phlebectasia.

Jugular phlebectasia is a rare cause of cervical swelling in children. It is a fusiform dilatation of any part of the jugular venous system and can involve the external, internal or anterior jugular veins. Previous reports suggest that the entity is often ignored or misdiagnosed. Unilateral internal jugular phlebactasia presenting as an intermittent neck swelling in a ten-year-old girl is reported. The clinical features are analyzed and the appropriate use of noninvasive imaging modalities is highlighted. The literature is also briefly reviewed.
