"Both anatomical and functional imaging of paragangliomas is required for diagnosis and staging. Anatomical imaging includes CT and MRI. Multiple functional imaging modalities exist: 123I-MIBG scintigraphy, 18F-FDA PET, 18F-DOPA PET, 18F-FDG PET and 68Ga-DOTATATE PET."

""Glomus" was historically used to describe certain neuroendocrine tumours arising from paraganglia, leading to the term glomus tumours for paragangliomas in older texts. The term is, however, imprecise and can be confused with the glomus bodies and tumours that arise from them, referred to as glomangioma (or glomus tumour) 19. It should thus be avoided."
"It is important to note that paragangliomas and phaeochromocytomas are closely related pathologically, developmentally, and functionally. The term phaeochromocytoma/paraganglioma is thus often used to group them together. This is the case in the WHO classification of endocrine and neuroendocrine tumours (5th edition), which then divides them into sympathetic paragangliomas and parasympathetic gangliomas, discussed below, and phaeochromocytoma, discussed separately 18."
"Von Hippel-Lindau syndrome and neurofibromatosis type 1 are more commonly associated with phaeochromocytomas. SDH mutations are common in head and neck paragangliomas, except for SDHB, which is associated with sympathetic paragangliomas. SDHB also confers a higher risk of malignancy 2,18."
"Paragangliomas are the most strongly hereditary group of tumours. The most common genetic cause of hereditary paragangliomas is mutations in the succinate dehydrogenase (SDH) subunit (genes: SDHB, SDHD, SDHA or SDHAF2) 2."
