Multifocal extra-adrenal paraganglioma evaluated with different PET tracers: comparison between 18F-FDG, 18F-DOPA and 68Ga DOTANOC PET/CT

Clin Nucl Med. 2013 Dec;38(12):e458-62. doi: 10.1097/RLU.0b013e31827088d9.

Abstract

A 40-year-old female patient with suspected multifocal extra-adrenal paraganglioma, on the basis of biochemical, genetic, and conventional imaging data, underwent 18F-FDG, 18F-DOPA and 68Ga DOTANOC PET/CT. FDOPA- and FDG-PET/CT detected a multifocal mediastinal and cervical paraganglioma. 68Ga-DOTANOC PET/CT detected 2 additional lesions compared to the other PET/CT methods. In our case, somatostatin receptor PET/CT with 68Ga-DOTANOC correctly assessed the extent of the disease in a patient with multifocal paraganglioma.
