68-year-old male with colon cancer ABDOMEN:LIVER, BILIARY TRACT: Numerous hepatic lesions have increased from the prior MRI but are similar to the recent CT. A left hepatic lobe lesion measures 2.1 x 1.9 cm, similar to the recent CT but new from the prior MRI. Localized intrahepatic ductal dilatation in the left hepatic lobe, similar to the prior exam. There is tumor abutting the right portal vein. Isointense signal within a small portion of the adjacent right portal vein likely represents volume averaging, as this appears patent on the same day CT. The main portal vein vein is narrowed by adjacent lymphadenopathy but is patent.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Multiple small cysts.RETROPERITONEUM, LYMPH NODES: Portacaval lymph node measures 2.2 x 1.3 cm (10/142), previously 1.8 x 1.1 cm on the prior MRI. Additional para-aortic nodes have increased since the prior exam.BOWEL, MESENTERY: Multiple mesenteric masses with a lesion anteriorly along the surgical scar measuring 2.9 x 3.6 cm (10/170). A left upper quadrant lesion measures 3.4 x 3.1 cm (10/128). An additional lesion is seen involving the descending colon. These are all increased from the prior MRI.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Elevation of left hemidiaphragm. Multiple right lower lobe pulmonary nodules with a prominent subpleural nodule measuring 1.0 x 0 cm (10/207), better evaluated on CT.
1.Hepatic and mesenteric metastases as well as retroperitoneal lymphadenopathy have increased since the prior MRI but are similar to the recent CT.2.Portal vein is narrowed but patent.3.Lung metastasis are better evaluated on CT.
