□Abstract

 A 64-year-old woman presented with a 4-year history of left-sided hearing loss and pulsatile tinnitus. On otolaryngological examinations, a reddish pulsating mass was seen through her left tympanic membrane. Computed tomography and magnetic resonance imaging revealed a well-enhanced soft tissue dentisity filling the mesotympanum. Bone destruction was not recognizable. The serum noradrenaline was elevated(584pg/ml)while adrenaline and dopamine were within normal limits. Under a preoperative diagnosis of glomus tympanicum tumor, she underwent selective embolization of the feeding arteries followed by transmastoid resection of the tumor, which was histopathologically diagnosed as paraganglioma. Her postoperative clinical course was uneventful, and the level of noradrenaline returned to normal. The patient is currently free from disease 17 months after surgery. Clinical and endocrinological characteristics of glomus tumors are bibliographically reviewed.
