All paraganglia are composed of chief cells (type I cells, ie, chemoreceptive cells) and sustentacular cells (type II cells, ie, supporting cells). Developmentally, both types of cells are of neuroectodermal origin; specifically, they arise from neural crest cells
The vast majority of glomus tumors are benign and slow to grow with bone erosion.
Coronal imaging can show tumoral relationships to the brainstem and skull base, and deep cervical soft-tissue structures
