Peptide Receptor Radionuclide Therapy by 177Lu-DOTATATE of a Secreting Cervical Paraganglioma.

A 59-year-old man with a parapharyngeal paraganglioma incidentally discovered on a cervical swelling was referred to our nuclear medicine department for a morpho-metabolic assessment. An 18F-FDG PET/CT was initially performed and found an intense hypermetabolism of the lesion and a hypermetabolism of the periadrenal brown fat evoking catecholamine secretion. An additional 68Ga-DOTATOC PET/CT was performed, showing an overexpression of the somatostatin receptors of this isolated paraganglioma.
