Fluorodeoxyglucose positron emission tomography-computed tomography scan in von Hippel-Lindau syndrome: A case report and review of literature
A 22-year-old gentleman with family history of RCC presented with hypertension. Sonography revealed right suprarenal mass. The echotexture of both the kidneys was normal. The urinary vanilyl mandelic acid was elevated. Iodine 131-metaiodobenzyl guanidine (MIBG) scan (not shown here) was normal. Fluorine 18-fluorodeoxyglucose positron emission tomography-computed tomography (F18-FDG PET-CT) scan revealed hypermetabolic right adrenal mass suggestive of pheochromocytoma []. There were no hypermetabolic renal cortical or pancreatic lesions. Subsequent high resolution computer tomography of the kidneys revealed multiple hypervascular cortical based lesions in the right kidney []. The pancreas was replaced by multiple cysts. Per operative needle aspiration from pancreas did not show malignant cells. Partial nephrectomy was done. Histology of the renal lesion showed clear cell carcinoma [].
