Multiparametric ultrasound evaluation of a case of bilateral carotid body tumor

AbstractParagangliomas are a rare form of highly vascularized tumors that originate from paraganglia Baysal (J Med Genet 39: 617–622, 2002). In the head and neck PGL arise primarily in four distinct areas: vagal, middle ear, and larynx and more frequently carotid bifurcation. Imaging evaluations include sonography, color Doppler, US-elastosonography and contrast-enhanced ultrasound (CEUS). Additionally, Computed Tomography, Magnetic Resonance Imaging (MRI) as well as digital subtraction angiography can be performed Stoeckli et al. (Laryngoscope 112: 143–146, 2002). We present herein a case of a rare bilateral carotid body tumor assessed with multiparametric ultrasound evaluation, including CEUS and US-elastography.

Carotid body tumors (CBT) are rare benign neoplasms of neural crest origin arising from paraganglia cells located at carotid bifurcation. They are usually treated with surgery and occasionally with radiotherapy (RT) as a definitive treatment. We report a case of a carotid body tumor (CBT) in a 45-year old woman who was treated with RT at another institution with intent of diminishing its size and eventually be operated later. This tumor, located on the left side of the neck, appeared 3 years before and was associated with dysphagia and odynophagia. A computed tomography (CT) revealed a lesion of 4.7 cm in size. The patient received 54 Gy of RT. As the tumor persisted clinically, an angio-CT performed one year later showed a left CBT of the same size and a contralateral lesion of 2cm. The surgical resection of this smaller right lesion was performed first and, of the persistent left lesion, one month later. No technical difficulties were found on the resection of the latter tumor and rather decreased peripheral vascularization was present. The histological findings revealed changes due to RT. In an exhaustive review of the literature, there were no findings of any report of surgical resection of a CBT after the primary RT.

Carotid body tumors (CBT) are a rare form of paragangliomas of the head and neck. They are described as rare, slow-growing, mostly benign, clinically silent tumors of neural crest cells. This tumor should be considered as a differential diagnosis when evaluating a lateral neck mass. A report of a rare case, a carotid body tumor, is presented that was incidentally noted as a lateral neck mass during a screening sonogram. A mass located at the level of the left carotid bifurcation demonstrated significant vascular flow with the use of contrast enhanced ultrasound (CEUS) techniques. Computed tomography angiography (CTA) was also performed to further analyze the tumor’s anatomical relation to the extra cranial vessels.

Benign Mass

A carotid body tumor is typically a benign mass and can have a low malignant potential. It can grow in between, attach to, or surround the internal carotid artery and external carotid artery in the neck. If this mass grows too big, it can compress the two arteries, causing problems in getting blood flow to the brain. The purpose for this sonography examination was to evaluate a patient with the following symptoms: dizziness, facial nerve injury, and sensorineural hearing loss. The carotid body tumor is a highly vascular tumor. This sonography examination provides a good opportunity to teach the importance of the use of color Doppler and proper documentation of this pathology that is often incorrectly documented with improper settings. This case reviews a 69-year-old Caucasian male with a carotid body tumor. The sonographic features, prevalence, common symptoms, prognosis, and treatments of the carotid body tumor are reviewed.
