Imaging Of Head And Neck Paraganglioma %R 10.22034/icrj.2018.75470 %X Paragangliomas of the head and neck originate most commonly from the paraganglia within the carotid body, vagal nerve, middle ear, and jugular foramen and also as glomus tumors  from paraganglion cells of neuroectodermal origin   near nerves and vessels. The function of most paraganglia in the head and neck is obscure Paragangliomas account for 0.6% of all neoplasms in the head and neck region, and about 80% of all paraganglioms are either carotid body tumors or glomus jugulare tumors. In this presentation we will discuss about  imaging of head and neck paraganglioma by focus on MRI and CTscan. %U
