We studied 15 cases of xanthogranulomatous cholecystitis (XGC) that were diagnosed from 633 specimens of gallbladder after cholecystectomy performed from January 1994 to June 2000. Preoparative ultrasonographic diagnoses of these cases were as follows: gallbladder cancer in 8 patients, gallstones in 5, and cholecystitis in 2. Patients were aged 54 to 83 year-old. The main symptoms were abdominal pain in 11 cases and high fever in 9 cases. Additionally, 13 cases were positive for CRP; leucocytosis exceeded 10 000 /mm3 in 5 cases; and serum CA 19-9 level was greater than 2000 IU/ml in 2 cases. Gallbladder wall thickness ranged from 2 to 15 mm, and ultrasonography showed gallstones in 14 cases. Although the characteristic ultrasonographic findings of XGC in previous reports included irregular wall thickening and hyperehoic lesions in the wall, wall thickening was not always present in the cases discussed here.
