71-year-old female patient with dilated common bile duct on abdominal ultrasound. Evaluate for stone/sludge/stricture leading to obstruction. Nausea/vomiting. ABDOMEN:LIVER, BILIARY TRACT: The gallbladder is absent. The common bile duct is dilated up to 14 mm in diameter with smooth tapering distally without evidence of an obstructing lesion; this is likely secondary to a postcholecystectomy state. There is minimal intrahepatic biliary ductal dilatation. A subcentimeter mildly T2 hyperintense lesion within the left hepatic lobe is too small to characterize, but possibly represents a cyst or hemangioma.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: There is a 1.3 cm exophytic lesion arising from the midpole of the left kidney with intermediate to low T2 signal; this is incompletely evaluated on single phase imaging.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: There is extensive body wall edema.OTHER: There is ascites and a large left pleural effusion.
1.Common bile duct dilatation without evidence of obstructing lesion is likely secondary to a postcholecystectomy state.2.Exophytic left renal lesion is indeterminate on single phase imaging; this can further evaluated with dedicated contrast enhanced renal imaging.3.Large left pleural effusion and ascites.
