Carotid Body Tumor (CBT): Incidental Discovery and Individualized Management

Abstract

Carotid Body Tumors (CBT) are uncommon neuroendocrine neoplasms that develop near the carotid bifurcation. Most cases are asymptomatic and discovered incidentally. Diagnosis is based on imaging, with computed tomography being the preferred initial investigation. Surgical excision is the preferred treatment, with preoperative embolization and angiography aiding in the planning process. In cases where surgery is not feasible, radiotherapy may be considered. Here we present a 75-year-old female with recurrent vomiting, severe headache, and newly diagnosed atrial fibrillation. Workup incidentally detected carotid body paraganglioma. The patient's treatment included metoprolol for heart rate and blood pressure control and radiotherapy for CBT due to age and comorbidities. The discussion delves into the characteristics of paragangliomas, their chemoreceptor role, prevalence, and genetic factors. The case report emphasizes the importance of early detection and individualized approaches in managing CBTs, considering patient profiles and medical conditions.
