Glomus intravagale

Abstract
Glomus intravagale (paraganglioma of the nodose ganglion and/or vagus nerve) is an unusual tumor. There are approximately 45 cases reported in the literature; the authors report four more cases. This tumor may ba associated with other paragangliomas of the head and neck, such as carotid body tumors, and may metastasize to regional lymph nodes, although the histology always appears benign.
