Internal jugular vein ectasia--a rare cause for paroxysmal cough.
Internal jugular vein ectasia (dilatation of the internal jugular vein) is a rare clinical entity, often undiagnosed. Usually it presents as an asymptomatic, soft, compressible neck swelling that increases in size on Valsalva's manoeuvre. Our report describes right internal jugular vein ectasia in a 15-year-old girl who presented to us with intractable paroxysmal cough. The entity was suspected on ultrasound imaging and confirmed by computed tomography scan and Doppler. Ligation and excision of the dilated vein almost immediately cured her cough. The probable reason for the cough was the pressure exerted by the dilated vein on the vagus nerve.
