71-year-old male with right hepatic lobe mass seen on outside ultrasound measuring 6.8 x 5.9 x 5.9 cm. ABDOMEN:LIVER, BILIARY TRACT: Normal surface contour of the liver. No specific evidence of cirrhosis.Large segment 8 lesion measuring 7.6 x 5.6 cm (image 11/series 6). demonstrates T1 hypointensity, mild T2 hyperintensity, restricted diffusion, and heterogeneous enhancement on delayed phase images, compatible with metastasis. Central T1 hyperintensity and T2 hypointensity with nonenhancement, most likely due to tumor necrosis with internal hemorrhage and/or proteinaceous material. Few additional scattered subcentimeter T2 hyperintense lesions are too small to characterize and may be due to cysts.No biliary ductal dilation.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Subcentimeter T2 hyperintense lesions in both kidneys are too small to characterize but likely due to cysts. RETROPERITONEUM, LYMPH NODES: Marked porta hepatis lymphadenopathy. Mild retroperitoneal and upper abdominal lymphadenopathy.BOWEL, MESENTERY: Enhancing annular mass in the proximal descending colon, most compatible with colon cancer (series 903/42).BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Annular mass in the proximal descending colon, most compatible with colon cancer.2. Large segment 8 hepatic lesion, most compatible with metastasis.3. Marked porta hepatis lymphadenopathy and mild upper abdominal and retroperitoneal lymphadenopathy.
