Imaging findings. a. Abdominal computed tomography scan shows 31×24 mm cystic lesion in right kidney (arrows). b. PET/CT scan showed moderate FDG accumulation of cystic lesion in right kidney (arrows). c. PET/CT scan showed moderate FDG accumulation of lung tumor (arrows). d. PET/CT scan showed moderate FDG accumulation of pancreatic body (arrows). e. Diffusion-weighted MRI showed high intensity area in pancreatic body (arrows). f. MRCP showed irregular narrowing in main pancreatic duct (arrows). g. PET/CT scan demonstrated a decrease of FDG accumulation in pancreatic body (arrows). h. PET/CT scan demonstrated a decrease of FDG accumulation in lung tumor (arrows).
