A Rare Case of Bilateral Carotid Glomus Jugulare with Partial Responses to Radiotherapy

Abstract

Glomus jugulare is known as a benign tumor that could involve in different parts of the body. The most prevalent site of involvement is head and neck area. This disease is rare and few of the cases are bilateral. However, in familial cases bilateral or multicenter lesions are even rarer, in which there is an autosomal dominant pattern of inheritance. The most efficient treatment is believed to be surgery or radiotherapy depending on the location and certain other factors, such as age and performance status. Sporadic bilateral lesion is rarely seen and most bilateral cases are familial. Herein, we reported a case of bilateral glomus jugulare of carotid with no history of this tumor in family or any other familial diseases. Our subject was a 67-year-old man. The diagnosis was made via Tru-cut biopsy. He was treated successfully by 3- dimensional conformal radiotherapy up to a dose of 60 Gy. The follow-up computed tomography scan revealed partial tumor responses. He had no family history of any systemic disease related to functional glomus jugulare, such as uncontrolled hypertention or mass in the neck. He also had no history of catecholeamine exceretion-related symptoms.
