[Duplex Doppler ultrasound of internal jugular vein ectasia. Case report].
A seven-year-old boy, who complained of painless swelling mass over the right neck on exertion, was diagnosed as right internal jugular vein ectasis by the duplex Doppler ultrasound. The caliber of the right internal jugular vein was prominently dilated when Valsalva maneuver was done, the duplex Doppler ultrasound showed an essentially flat wave from that indicated the swelling mass to be a venous structure. The clinical manifestation, etiology, pathological findings and diagnostic methods of the internal jugular vein ectasia were reviewed with emphasis on the advantages of duplex Doppler ultrasound in confirming the diagnosis.
