Role of 68 Ga-DOTATATE PET/CT in a Case of SDHB -Related Pterygopalatine Fossa Paraganglioma Successfully Controlled with Octreotide

We describe an unusual case of a 42-year-old female with an unresectable succinate dehydrogenase subunit B ( SDHB) -related pterygopalatine fossa paraganglioma. She underwent somatostatin receptor imaging with 68 Ga-DOTA(0)-Tyr(3)-octreotate ( 68 Ga-DOTATATE) positron emission tomography/computed tomography (PET/CT), which showed uptake in the above mentioned tumor. Hence, the patient was started on octreotide, a cold somatostatin analog, and responded with tumor stabilization and improvement of clinical symptoms for 36 months since initiation of octreotide therapy. This case demonstrates the role of 68 Ga-DOTATATE PET/CT in diagnostic localization and its subsequent role in treatment using cold somatostatin analog as a potential choice of therapy in the management of paraganglioma in an unusual location with limited therapeutic options.
