78-year-old male status post cholecystectomy and biliary exploration with abdominal pain. Evaluate for biliary stenosis. ABDOMEN:LIVER, BILIARY TRACT: Status post cholecystectomy. No intra-or extrahepatic biliary ductal dilation. There is a 1.2-cm focus of fluid signal intensity in the expected region of the gallbladder fossa (24; series 8). The common bile duct measures up to 7 mm in diameter. SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Multiple bilateral simple cysts are identified within the kidneys bilaterally. Subcentimeter foci of fluid signal intensity are identified within the kidneys, which are too small to characterize, but also likely represent simple cysts.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Small hiatal hernia. Incidental note is made of a periampullary duodenal diverticulum.BONES, SOFT TISSUES: Note made of moderate to severe spinal canal stenosis with partial effacement of the thecal sac at the level of T10/T11. A dedicated MRI of the thoracic spine could be considered if clinically indicated. OTHER: No significant abnormality noted.
1. Nonspecific 1.2 cm focal fluid collection in the gallbladder fossa. No evidence of biliary stenosis as clinically, questioned. 2. Degenerative changes, as described above.
