65 year-old female with negative germline mutation testing. The patient had a right glomus vagale with metastatic disease to lymph nodes, bone and liver evident on Ga-68 DOTATATE (a), F-18 FDG (b) but not I-123 MIBG (c). One of the hepatic metastases, however, was seen on FDG but not on other imaging modalities (arrow). The lower physiologic background activity on FDG may result in increased detection rate compared to DOTATATE in some patients
