case_images: Gadolinium-enhanced total abdomen MRI images of an 83-year-old patient with lesions in the pancreas and renal pelvis on November 15th, 2021. The lesion located in uncinate process of head of pancreas showed gradual enhancement on T1-weighted image (A, red circle and arrow). The main pancreatic duct was widened. Lesion (MD = 2.3 cm) in the right renal pelvis showed mild, uneven enhancement (B, red circle and arrow).

case_images: A nodule, 23x16x18 mm, was found in the uncinate process of the pancreas (Figure 1A). In addition, a right renal pelvis nodule, 23x9 mm with clear boundary, was found (Figure 1B).
case_images: Three-dimensional ultrasound images with lesion in the pancreas on November 12th, 2021. The superior common bile duct was obviously dilated with MW of 1.8 cm (A, dotted line). The gallbladder volume was enlarged with a 7.9 cm long diameter and 4.14 cm front and back diameter (B, dotted line). The main pancreatic duct was also widened with MW of 1.06 cm (C, dotted line). The lesion located in head of pancreas area was 1.71 cm (D, dotted line) in MD.

case_images: The results of three-dimensional ultrasound images (detected on November 12th 2021) of the whole abdomen also showed that the gallbladder was enlarged (about 79x41 mm) with clear outline, the intrahepatic bile duct was dilated, and the downward part of the common bile duct was widened to about 18 mm (Figure 2A and B). The main pancreatic duct was dilated (about 11 mm, Figure 2C) and coupled with low biliary obstruction (Figure 2D).
case_images: Gadolinium-enhanced total abdomen MRI images with lesions in the pancreas and renal pelvis on November 7th, 2022. The lesion located in uncinate process of head of pancreas still showed gradual enhancement on T1-weighted images (A, red circle and arrow). Lesion (MD = 2.2 cm) in the right renal pelvis showed slightly higher signal on T2-weighted image (B, red circle and arrow).

case_images: MRI scan images (detected on November 7th 2022) showed extremely encouraging results: no further growth of either tumor compared with the MRI results of November 15th 2021, with the current size of the pancreatic tumor being 23x16 mm (Figure 3A) and that of the right renal pelvis tumor being 22x9 mm (Figure 3B), unambiguously demonstrating that the patient's diseases were under effective control.
