History of new ulcerative sigmoid colon mass seen on colonoscopy, evaluation of hepatic lesion seen on prior CT imaging ABDOMEN:LIVER, BILIARY TRACT: Corresponding to hypodensity seen on prior CT imaging is hepatic segment II focus of abnormal signal measuring 1.8 x 1.2 cm, which demonstrates mildly increased T2 signal and restricted diffusion as well as postcontrast rim enhancement (pattern of enhancement appears to be continuous and somewhat nodular). Although postcontrast enhancement difficult to delineate due to small size, additional smaller adjacent foci demonstrating similar signal characteristics otherwise seen, measuring up to 0.7 x 0.5 cm, image 27 series 401, suspicious for additional nearby metastatic foci. Another tiny focus of restricted diffusion seen in right hepatic dome, image 328 series 501, difficult to assess for postcontrast enhancement and T2 signal abnormality due to small size, nonspecific but a metastatic lesion not entirely excluded. Best seen in the portal venous phase of imaging is a 1.3 x 1.2 cm left hepatic dome focus, hypointense compared to background liver during this phase (image 364 series 901), indeterminate, no corresponding restricted diffusion delineated. A T2 hyperintense focus lateral to gallbladder fossa located in hepatic segment 5 may be a cyst, image 274 series 901.SPLEEN: Multiple soft tissue signal lesions in expected region of spleen/splenic bed, suggestive of splenosis.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Right upper pole renal cyst. Multifocal left renocortical scarring.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.
