Internal Jugular Vein Phlebectasia in a Child: A Case Report.

Neck swellings that appear on straining, crying, and Valsalva maneuver are usually suggestive of laryngocele. Phlebectasia of jugular veins can cause a similar sign but is rare compared to laryngocele. Jugular vein phlebectasia (JVP) is of unknown etiology and is caused by vein dilatation without tortuosity, which is rare in children.
