Figures
- FIGURE 1.
Patient 5 with SDHD mutation–related HNPGLs. 68Ga-DOTATATE PET/CT (A) demonstrates lobulated finding in CB region on left side and additional lesion in GV region and in JT region on left side. JT findings are not visible on 18F-FDOPA PET/CT (B). 18F-FDG PET/CT (C) faintly demonstrates left CB and very faintly GV on left side. White arrow points to uptake in vocal cord. 18F-FDA PET/CT (D) is completely negative.
- FIGURE 2.
Patient 19 with SDHD mutation–related HNPGLs. 68Ga-DOTATATE PET/CT (A) demonstrates big mass in GV region on right side and additional lesion in CB region on right (white arrow). Finding in CB region is not visible on 18F-FDOPA PET/CT (B). On 18F-FDG PET/CT, only GV lesion is seen faintly (C). 18F-FDA PET/CT (D) is negative.

(A) Common sites of HNPGLs (black). (B) Localization of 7 lesions detected only on 68Ga-DOTATATE in our study (green). ACE = external carotid artery; ACI = internal carotid artery; CBP = carotid body paraganglioma; FC = carotid foramen; FJ = jugular foramen; JTP = JT paraganglioma; VP = vagale paraganglioma.
