Epididymal Cystadenomas in von Hippel-Lindau Disease Showing Increased Activity on Ga-68 DOTATATE PET/CT

摘要

von Hippel-Lindau (VHL) disease is a familial cancer syndrome characterized by the development of a variety of malignant and benign tumors, including epididymal cystadenomas. We report a case of a VHL patient with bilateral epididymal cystadenomas who was evaluated with Ga-68 DOTATATE PET/CT, showing intensely increased activity (SUVmax, 21.6) associated with the epididymal cystadenomas, indicating cell-surface overexpression of somatostatin receptors. The presented case supports the usefulness of somatostatin receptor imaging using Ga-68 DOTA-conjugated peptides for detection and follow-up of VHL manifestations, as well as surveillance of asymptomatic gene carriers.
