Glomus Tympanicum Tumor – A rare presentation in a tertiary care hospital of Peshawar
Abstract
INTRODUCTION: Glomus tympanicum tumor is a benign but most common tumour of the middle ear with relatively good prognosis if detected early. These tumours arise from paraganglionic tissue and are innervated by parasympathetic autonomic nervous system (PANS). They are more common in females. The spread of these tumours is multidirectional and simultaneous. They may be asymptomatic or present with pulsatile tinnitus. On examination, the eardrum shows a rising sun or setting sun appearance. On CT scan, we can see a soft tissue mass lateral to the cochlear promontory which may fill the middle ear cavity. Surgical resection is the treatment of choice.
We present a case of 40 years old anemic female who presented to us with a history of constant pain, progressive left ear hearing loss and a mass in left ear for the last 3 months. On CT, we saw a soft tissue density lesion enhancing the middle ear and protruding into the external ear.
