Abstract

Carney triad is a very rare syndrome characterized by the synchronous or metachronous occurrence of gastrointestinal stromal tumors, pulmonary chondroma, and extra-adrenal paraganglioma. We present the case of a 36-year-old woman with complete Carney triad who underwent a 68Ga-DOTA-TATE PET/CT scan for restaging of metastasizing extra-adrenal paraganglioma and for evaluation of targeted radionuclide therapy potential. On the 68Ga-DOTA-TATE PET scan, increased tracer accumulation was observed in paraganglioma metastases. This case highlights the usefulness of 68Ga-DOTA-TATE PET/CT for restaging of metastasizing paraganglioma in Carney triad and the option of targeted radionuclide therapy in this entity.
