Renal and pancreatic cysts and tumors are the most common visceral manifestations of von Hippel-Lindau (VHL) disease, a heritable multisystem cancer syndrome characterized by development of a variety of malignant and benign tumors. We report a case of a VHL patient with multiple renal cystic and complex cystic/solid lesions. The patient underwent 68Ga-DOTA-TATE-PET/CT showing intensely increased activity by a solid lesion which demonstrated enhancement on both CT and MRI scans, raising high suspicion for malignancy. The presented case indicates application of SSTR-imaging using 68Ga-DOTA-conjugated peptides in VHL-patients and emphasizes the need for cautious interpretation of renal parenchyma 68Ga-DOTATATE activity.
