Glomus tumors or paragangliomas are rare benign neoplasms which are very uncommon in the head and neck region. They grow slowly from paraganglion cells, which serve various regulatory tasks in the body and form the basis of the extra-adrenal neuroendocrine system. They have benign properties, but tend to cause local invasion and expansion to adjacent anatomic structures. The majority of glomus tumor cases are incidental findings, since the clinical symptoms are mostly absent. The purpose of this paper is to distinguish the ultrasonographic features of different glomus tumors located within the neck region, based on their varying anatomical location and space occupying behavior.
