Carotid Body Tumors

This case report illustrates two unusual cases of parapharyngeal schwannomas mimicking carotid body tumors in terms of characteristic vascular displacement. Carotid body tumors classically cause splaying of internal and external carotid arteries demonstrating the Lyre sign on imaging. Also interestingly, both of these cases were seen in younger ages and include cervical sympathetic chain schwannoma and vagal schwannoma. However, these schwannomas revealed hypovascularity on imaging studies allowing differentiation from hypervascular carotid body tumors. Preoperative distinction between carotid body tumors and schwannomas is very important.

Carotid body tumor (CBT), the most common tumor of the carotid bifurcation, presents as a pulsatile mass. Cervical sympathetic chain (CSC) schwannomas are slow growing lesions originating from myelin-producing Schwann ceils. They may appear pulsatile due to the displacement of vascular structures by the non-vascular mass and thus may mimic a CBT. A case of CSC schwannoma masquerading as CBT in a 25-year-old woman is presented and discussed here.

The cervical sympathetic chain (CSC) innervates post-ganglionic sympathetic neurons within the ipsilateral superior cervical ganglion (SCG) of all mammalian species studied to date. The post-ganglionic neurons within the SCG project to a wide variety of structures, including the brain (parenchyma and cerebral arteries), upper airway (e.g., nasopharynx and tongue) and submandibular glands. The SCG also sends post-ganglionic fibers to the carotid body (e.g., chemosensitive glomus cells and microcirculation), however, the function of these connections are not established in the mouse. In addition, nothing is known about the functional importance of the CSC-SCG complex (including input to the carotid body) in the mouse. The objective of this study was to determine the effects of bilateral transection of the CSC on the ventilatory responses [e.g., increases in frequency of breathing (Freq), tidal volume (TV) and minute ventilation (MV)] that occur during and following exposure to a hypoxic gas challenge (10% O2 and 90% N2) in freely-moving sham-operated (SHAM) adult male C57BL6 mice, and in mice in which both CSC were transected (CSCX). Resting ventilatory parameters (19 directly recorded or calculated parameters) were similar in the SHAM and CSCX mice. There were numerous important differences in the responses of CSCX and SHAM mice to the hypoxic challenge. For example, the increases in Freq (and associated decreases in inspiratory and expiratory times, end expiratory pause, and relaxation time), and the increases in MV, expiratory drive, and expiratory flow at 50% exhaled TV (EF50) occurred more quickly in the CSCX mice than in the SHAM mice, although the overall responses were similar in both groups. Moreover, the initial and total increases in peak inspiratory flow were higher in the CSCX mice. Additionally, the overall increases in TV during the latter half of the hypoxic challenge were greater in the CSCX mice. The ventilatory responses that occurred upon return to room-air were essentially similar in the SHAM and CSCX mice. Overall, this novel data suggest that the CSC may normally provide inhibitory input to peripheral (e.g., carotid bodies) and central (e.g., brainstem) structures that are involved in the ventilatory responses to hypoxic gas challenge in C57BL6 mice.

Schwannomas are benign, slow-growing tumors that arise from Schwann cells of the nerve sheath. Those originatingfrom the sympathetic cervical chain are extremely rare and usually presents as an asymptomatic neck mass. Here we report a case ofschwannoma of the cervical sympathetic chain in a 32-year-old man who had asymptomatic neck mass for 6 months. But it appearedpulsatile due to the anterior displacement of carotid sheath by the mass and thus mimics a carotid body tumor. As discussed in this reportCT scan with contrast is enough for ruling out paraganglioma and imposing extra expense for MRI and angiography is unnecessary .Theonly rare complication encountered after surgery was Horner's syndrome, which required no treatment.
