Here, we present a case of IJV phlebectasia of a girl in her early childhood, highlighting its clinical presentation, diagnostic workup and management. The patient presented with a painless, non-pulsatile neck mass, which was identified as an enlarged IJV on imaging studies. Since it is a benign condition, and the patient is asymptomatic, observation with regular monitoring is advised.
