(GA) is a disease characterized by epithelial proliferation and hypertrophy of the muscles of the gallbladder wall (1) with an outpouching of the mucosa into or through the thickened muscular layer, i.e., the Rokitansky-Aschoff sinuses (RAS) (2).
They include early-stage cancer and advanced cancer that has advanced to the SS stage or further, in addition to nonneoplastic lesions of the adenomyomatosis
(ADM) and xanthogranulomatous cholecystitis (XGC) (Figures 1(c) and 1(d)).
Imaging features of neoplastic masses may be difficult to distinguish from sludge, hematoma, mucosal folds, adherent cholesterol polyps, adenomyomatosis
, or inflammatory polyps .
It can be secondary to primary gallbladder pathology such as acute and chronic cholecystitis, adenomyomatosis
, or gallbladder carcinoma .

35 patients with pancreatic cancer, 12 patients with biliary tract cancer (Table 1), and a control group consisting of 31 patients with benign pancreatobiliary diseases (13 with common bile duct stones, 6 with chronic pancreatitis, 4 with benign bile duct stricture, 2 with pancreatic pseudocyst, 2 with autoimmune pancreatitis, 2 with adenomyomatosis
of the gallbladder, 1 with pancreatobiliary maljunction, and 1 with benign pancreatic duct stricture) (Table 2) that had been hospitalized for treatment at this institution between December 2010 and April 2011 were entered into this study.
