“…Populations living at higher elevations or in a chronic hypoxic state are thought to have a higher incidence of paragangliomas. [18][19][20] The clinical prognosis of carotid body tumors is usually favorable due to their location and relative accessibility for surgical resection. 21 However, surgery can be challenging because the tumor is highly vascular and often densely adherent to the carotid bifurcation with intimate association of cranial nerves X and XII.…”

BACKGROUND AND PURPOSE: Advances in multidetector CT provide exquisite detail with improved delineation of the normal anatomic structures in the head and neck. The carotid body is 1 structure that is now routinely depicted with this new imaging technique. An understanding of the size range of the normal carotid body will allow the radiologist to distinguish patients with prominent normal carotid bodies from those who have a small carotid body paraganglioma.

“…Usually, CT and computed tomographic angiography (CTA) scans, magnetic resonance (MR) and magnetic resonance angiography (MRA) imaging, conventional ultrasounds, color Doppler ultrasounds and carotid conventional angiography (CA) are used (22). The CT images best revealed the shape, size, margin, blood supply and adjacent infiltrations of the tumor in the present case.…”

Abstract. Carotid body tumors (CBTs) are a rare type of extra-adrenal paraganglioma, which originate from the carotid body. A 29-year-old woman was admitted to the Department of Head and Neck Surgery, Beijing Tongren Hospital (Capital Medical University, Beijing, China) with hoarseness of the throat, which had progressively worsened over seven months. The patient had a family history of CBTs. Computed tomography and ultrasound imaging revealed multiple well-enhanced masses located at the bilateral carotid bifurcation and in the left parapharyngeal space. Surgery and pathological examination confirmed that the patient had developed regional lymph node metastasis. Significantly enhanced multiple pulmonary and hepatic lesions indicated that the patient had also developed distal metastasis. A genetic analysis performed on the family members of the patient revealed that the family carried a mutated succinate dehydrogenase D gene. In the present study, a systemic review of the literature indicated that extra vigilance is required in familial forms of CBT, in order to increase the standard of treatment for CBT patients.

“…In particular, a previous study showed that the hemodynamic analysis obtained using CTA contributed to the accurate evaluation of the morphology of the vascular wall and the identification of tumor invasion to the middle layer and tunica intima of the carotid wall (14). According to our previous clinical experience, we recommend complete evaluation of tumor invasion to the carotid artery prior to the surgery and, concomitantly, appropriate evaluation of brain ischemic tolerance in order to evaluate whether the cerebral collateral circulation has been established.…”

Abstract. The aim of the present study was to illustrate the diagnosis and treatment of carotid body tumor (CBT) based on our experience of previous patients. A total of 58 patients (62 lesions) with CBT who received surgery between October 2003 and October 2013 were included. In total, 17 lesions were categorized into Shamblin grade I, 33 were grade II, and 12 were grade III. Surgical resection of CBT was performed for 52 lesions, resection of CBT and the external carotid artery was performed for 9 lesions, and resection of CBT and the internal carotid artery was performed for 1 lesion. No hemiplegia was observed. Hoarseness and bucking were observed in 2 patients of Shamblin grade III, and were eliminated 1 month subsequent to the administration of hormone therapy and a nerve-nurturing strategy. No relapse or mortality was observed during the follow-up. In conclusion, surgical resection of CBT is recommended following diagnosis. The evaluation of imaging features and cerebral collateral circulation is important for treatment.
