Male 47 years old with metastatic colon cancer. Reevaluate liver metastases. Additional history from the electronic medical record indicates resection of the segment 7 liver lesion in September 2016. ABDOMEN:LIVER, BILIARY TRACT: At the site of the previously seen hepatic segment 7 lesion there is a larger fluid signal cavity consistent with interval resection. There is a subcentimeter nodular focus of enhancement along the medial aspect of the cavity (image 44 of series 10011) favored to represent vessels as seen on image 46 of series 10011 but attention to this region on follow-up imaging is recommended. Surrounding small T1 hyperintensity and susceptibility artifact consistent with postoperative change. The 1 mm T2 hyperintense cyst in hepatic segment 6 is unchanged and likely benign. No new focal hepatic lesions are identified.The hepatic vasculature appears patent. Status post cholecystectomy. No intra or extrahepatic biliary ductal dilatation.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Moderate right hydroureteronephrosis appears unchanged as do subcentimeter renal cysts.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Postsurgical changes are seen in the anterior abdominal wall. Nodularity along the deep margin of the inferior left rectus muscle on the outside hospital CT 8/12/2016 is not included in the field-of-view on today's MRI.OTHER: No significant abnormality noted.
1.Status post hepatic segment 7 metastasis resection. A subcentimeter nodular focus of enhancement along the resection cavity is favored to represent vessels however attention to this region on follow-up imaging is recommended.2.No new hepatic lesions.3.Stable moderate right hydroureteronephrosis.
