Presentation
Three-month history of diffuse abdominal pain and weight loss of 20 kilograms.
Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.

Plain radiograph demonstrates calcification of a near-spherical structure in the right upper quadrant most likely representing the gallbladder.

A computed tomographic scan showed that the calcification seen on the plain abdominal radiograph represented the wall of the gallbladder. The scan also showed ascites, multiple lesions in the liver, and nodularity of the peritoneum and small bowel mesentery. These findings suggested metastatic carcinoma of the gallbladder, but the patient refused further investigation.
Case Discussion
On physical examination, she had a hard, non-tender, baseball-sized mass in the right upper abdominal quadrant.
