68 year-old male. PSC, abnormal MRI. Assess ? obstructing lesion. ABDOMEN:LUNG BASES: Enlarged right cardiophrenic lymph node, unchanged. LIVER, BILIARY TRACT: Cirrhotic nodular liver morphology. Disproportionate atrophy of the left hepatic lobe relative to the right. Beaded ductal dilatation of the bilobar intrahepatic ducts consistent with PSC, unchanged.Mildly hypointense lesion in the left hepatic lobe adjacent to a dilated duct noted on 11/2014 MRI measures 1.7 x 0.8 cm (series 15, image 145), previously 1.6 x 0.8; this lesion is isointense to hepatic parenchyma on delayed phase images and is favored to be a perfusion abnormality.

Small splenules noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Subcentimeter right renal hemorrhagic cyst.RETROPERITONEUM, LYMPH NODES: Mildly enlarged periportal lymph nodes, unchanged. BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: A small amount of abdominal ascites.
