Synchronous intracholecystic papillary-tubular neoplasm and pancreatic intraductal tubulopapillary neoplasm: A case report

Figure 1 Contrast-enhanced computed tomography findings. A: The gallbladder shows multiple soft-tissue lesions along the gallbladder wall and heterogeneous enhancement of a giant gallbladder; B: The pancreas shows multiple cystic-solid lesions distributed from the pancreatic head to the tail.

Figure 2 Positron emission tomography/computed tomography findings. A: A cystic-solid mass in the gallbladder fossa shows a maximum standardized uptake value of 11.1; B: Multiple cystic-solid pancreatic masses show indistinct boundaries and heterogeneous uptake, with a maximum standardized uptake value of 7.9.

Figure 3 Histopathological features of gallbladder intracholecystic papillary-tubular neoplasm and pancreatic intraductal tubulopapillary neoplasm. A: The gallbladder lesion shows an intraluminal papillary-tubular neoplastic proliferation with high-grade dysplasia; B: The pancreatic lesion shows predominantly intraductal epithelial neoplasm composed of tightly packed tubular and tubulopapillary structures with multifocal invasive carcinoma infiltrating the pancreatic parenchyma.
