Internal jugular phlebectasia communicating with a cervicomediastinal lipoma: a case report

Venous aneurysms are an atypical presentation of neck masses in the paediatric population. The evaluation and surgical removal of internal jugular vein phlebectasia and a lipoma coexisting are described in this report. Internal jugular vein phlebectasia is theorised as a congenital defect and is becoming more common with advancing imaging technologies. Both phlebectasia and lipomas are considered benign conditions, but clinicians must be aware of tumours producing mass effect.
