Phlebectasia describes an anomalous, fusiform dilatation of a vein. In the neck region, the internal and external jugular veins are mostly affected. To our knowledge, this is the first case in Saudi Arabia of internal jugular phlebectasia affecting an adult female. We describe a 61-year-old female with complaints of a neck swelling she noticed 4 years ago. Initially, the swelling increased in size and reached a stable level. It was asymptomatic and only enlarged during Valsalva maneuver. Flexible nasolaryngoscopy and computerized tomography scan showed unremarkable examination. Follow-up after 1 year with US Doppler showed no progression. Internal jugular phlebectasia is a rare disorder which is often diagnosed during childhood. More often than not, it does not cause any significant morbidity. Since it is a benign condition, observation is advised with regular monitoring. For asymptomatic lesions, surgical intervention is recommended if cosmetic or psychologic concerns are present.
