75-year-old female with elevated liver function enzymes who presents for evaluation for any obstructive lesion or hepatic parenchymal disease. ABDOMEN:LIVER, BILIARY TRACT: Noted is a subcentimeter segment 7 T2 intermediate intensity, T1 hypointense lesion without contrast enhancement; this is most likely benign.The common bile duct is slightly irregular without obvious obstructing lesion. There is mild intrahepatic biliary ductal dilatation, most obvious on the left. No definite connection between the left intrahepatic biliary duct and the common bile duct is identified. However, there is no obvious mass.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: T2 hyperintense subcentimeter left renal foci without evidence of enhancement compatible with cysts. Additionally, there is a T1 hyperintense, T2 hypointense nonenhancing subcentimeter left renal focus, most compatible with a proteinaceous cyst. No suspicious renal lesions.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: There is a peripherally calcified, T1 and T2 isointense focus anterior to the left inferior renal pole measuring 2.1 x 1.9 cm (series 12, image 78). This lesion does not demonstrate dropout on in and out of phase. There is additionally no evidence of enhancement.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Slightly irregular common bile duct with mild intrahepatic biliary ductal dilatation. No definite connection between the left intrahepatic biliary duct and the common bile duct is identified. However, there is no obvious mass is noted. If there is clinical concern, further evaluation with ERCP to evaluate for inflammatory etiology may be considered.2.Subcentimeter segment 7 nonenhancing lesion as detailed is most likely benign.3.Left upper quadrant mesenteric peripheral calcified nonenhancing focus is most likely benign in etiology.
