Figure 2
Head-to-head comparison of 18F-FDOPA PET/CT, 68Ga-DOTATATE PET/CT, CT, T1 SE Gado MR, and angiography MR sequences in a multifocal SDHD-related PGL. Axial anatomical and functional images centered over the jugular foramen: red arrow: right JP, black arrow: left JP. Note that the small right JP (red arrow) is missed by angio CT and T1 SE Gado sequence due to the gadolinium enhancement of the right internal jugular vein. By contrast, early arterial images on 4D MR angiography or TOF angiography images have detected this tiny PGL (red arrow). In the present case, the MR imaging protocol was adjusted according to the functional imaging findings. Note the higher tumor uptake with 68Ga-DOTATATE compared to 18F-FDOPA.

Figure 4Functional imaging findings in a case of adrenal lymphoma and a case of metastatic pheochromocytoma. (A) Adrenal lymphoma with a mediastinal lymph node (arrows). (B) Sporadic pheochromocytoma with a metastatic mediastinal lymph node (arrows). This patient's tumors have rapidly metastasized to the lungs. Note the similar 18F-FDG PET/CT presentation in both cases. As expected, the PHEO was positive for 18F-FDOPA.

Figure 5Functional imaging findings in a case of extraadrenal sympathetic SDHB-related PGL. Multimodality imaging with 123I-MIBG (anterior and posterior views), SRS (three images), and 18F-FDG PET/CT. The PGL (arrow) was moderately avid for Octreoscan and quasi-negative on MIBG scan. In contrast, the tumor exhibited high 18F-FDG uptake, a finding that is typical for SDHB-tumors.
