History of metastatic colon cancer. Lack of intravenous contrast limits evaluation for solid organ, bowel and vascular pathology. LUNG BASES: Multiple T2 hyperintense lung masses are noted and are suspicious for metastatic disease. A left lung base mass measures 1.9 x 1.9 cm (series 701/37).ABDOMEN:LIVER, BILIARY TRACT: Several right hepatic lobe T2-weighted moderately and very hyperintense lobular lesions are suspicious for metastatic mucinous colonic adenocarcinoma given the patient's history. A representative lesion in segment 8 measures 2.0 x 1.9 cm (series 701/34). No biliary ductal dilatation.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Multiple T2 hyperintense foci are incompletely characterized, likely cysts. Mildly hypointense T2 weighted foci are incompletely characterized and may represent proteinaceous/hemorrhagic cysts. No hydroureteronephrosis.RETROPERITONEUM, LYMPH NODES: No enlarged retroperitoneal lymphadenopathy.BOWEL, MESENTERY: Postsurgical changes from right hemicolectomy. No evidence of obstruction or fluid collection.BONES, SOFT TISSUES: Mottled marrow signal intensity is nonspecific.
Limited nonenhanced examination demonstrates the following.1.Suspected multiple right hepatic lobe metastases and multiple lung metastases which are partially imaged. New from 2012.2.Stable left external iliac T2 hyperintense lymphadenopathy.
