59-year-old male with history of PSC. Evaluate for obstruction. ABDOMEN:LIVER, BILIARY TRACT: Redemonstrated are multifocal areas of extensive dilatation and stricturing of the intrahepatic bile ducts particularly in the left hepatic lobe. The most dilated duct measures 5 mm today. There is left hepatic lobe atrophy. Persistent periductal enhancement is appreciated bilaterally. The common bile duct appears unremarkable. No suspicious masses identified. Unchanged segment 8 nonenhancing cyst.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Status post left nephrectomy.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Right lower lobe scarring/atelectasis.
