tumor (chemodectoma) clinicopathologic analysis of ninety cases.
A carotid body tumor usually presents headache or neck pain in 35%, dizziness in 8%, hoarseness in 8% and dysphagia in 8% of patients.
The presence of a pulsatile neck mass located in the region of carotid triangle and generally present for several years should suggest the presence of a carotid body tumor.
Carotid body tumours, for example, may be associated with phaeochromocytoma , however vagal paragangliomas are more commonly seen in familial syndromes, and are more likely to be multifocal.
This case demonstrates that differential diagnoses should be considered even when distinctive imaging characteristics of carotid body tumour are found.
13,14) Carotid body paragangliomas are also more common in women.
Four of these patients had a carotid body tumor, 2 had a glomus tympanicum tumor, and 3 had a glomus vagale tumor (table).
Other investigators (4,7,8) have reported that papillary carcinomas of the thyroid, a leiomyoma, and schwannomas (among others) have appeared as carotid body
tumors, but we have not seen any report of an undifferentiated mass that mimicked a carotid body
Magnetic resonance angiography (MRA) (figure 1, C) and duplex Doppler ultrasonography better demonstrated the splayed appearance of the carotid branches, and the appearance was thought to be most consistent with a carotid body
Embolization: An adjunctive measure for removal of carotid body
tumors must be differentiated histologically from other similar-appearing neoplasms, including medullary thyroid carcinomas, laryngeal neuroendocrine neoplasms, and metastatic carcinomas, particularly renal cell carcinomas.

tumors: Long-term survival, recurrence, and metastasis.
