Abstract

Paragangliomas are uncommon tumors that arise from the parasympathetic neuroectodermal ganglionic cells and have been described in numerous anatomic locations, most commonly in the abdomen. Head and neck paragangliomas are classified into carotid body (most common), vagal, and jugulotympanic types. Computed tomography is the initial imaging modality of choice for the preoperative assessment of the extent of paragangliomas. Magnetic resonance imaging and selective angiography provide more detail of the surrounding tissues and vasculature. Surgical resection is the treatment of choice.
