A Case Report of a Four-Year Old Male Patient with Phlebectasia that Dilatates with Vocalization

Local dilatation of blood vessels can occur in arteries, veins, or lymphatic vessels. Varicose veins that occur in the neck are even rarely reported. For neck mass found in children, when the size of the swellings increases during the Valsalva maneuver, chances are that there are the upper mediastinal tumors and/or cyst, laryngeal cyst or jugular venous ectasis. The child in this report showed a pain-free bulging on the neck that appears only when speaking and disappears when not. The cervical Doppler ultrasonography and computed tomography showed that the right internal jugular vein expanded up to 3×2 cm. There were no abnormalities detected on the palpation and no other specific findings except for bulging. This was a rare case of a child with jugular venous ectasis. We regarded it as a benign lesion and decided to monitor the case 6-months later without a surgical resection as we considered it not necessary.
