History of stage IV appendiceal cancer on chemo pre-op evaluation for metastases and response to chemotherapy. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology and parenchymal signal intensity. A few scattered cystic lesions measuring less than 5 mm in the right lobe of the liver are too small to characterize but appear grossly similar to 8/12/2015 CT. No suspicious hepatic lesions are identified. No biliary ductal dilatation.SPLEEN: No significant abnormality noted. Splenules are present.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: There are areas of abnormally increased DWI signal within the omentum suspicious for carcinomatosis most prominent in the left upper quadrant (series 5, image 23) and to a lesser extent the right lower quadrant (series 19, image 69). There is also subtle omental nodularity seen on T2-weighted images in the anterior aspect of the right lower quadrant which was also described on prior CT. Overall, the amount of omental disease appears to have decreased compared to the 8/12/2015 CT.BOWEL, MESENTERY: The bowel is normal in caliber without evidence of obstruction. The appendix is not definitively visualized.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Omental nodularity overall decreased compared to 8/12/2015 CT allowing for differences in technique and compatible with stated history of stage IV appendiceal cancer.
