Pulsatile Tinnitus Caused by Internal Jugular Phlebectasia in an Adult.
AbstractInternal jugular phlebectasia is a rare condition. Children with internal jugular phlebectasia are often discovered by their parents when they notice a soft mass in the neck that appears when the child cries, coughs, or breathes deeply. Most internal jugular vein dilatations occur unilaterally on the right side according to the literature reports. To our knowledge, no other internal jugular phlebectasia patients reported pulsatile tinnitus as the major complaint without a soft mass in the neck. The authors reported a female adult patient with left-side internal jugular phlebectasia with pulsatile tinnitus as the major complaint without a soft mass in the neck. Internal jugular phlebectasia was diagnosed by color ultrasound of the internal jugular vein. Pure-tone audiometry, tympanometry, hemoglobin, thyroid function, and magnetic resonance imaging were made to differentiate other diseases that can cause the pulsatile tinnitus. Conservative treatment is recommended in this report. The possibility of internal jugular vein dilatation should be considered when differentiate the possible diseases that caused pulsatile tinnitus.
