History of retroperitoneal liposarcoma. Follow-up exam. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology. There is minimal diffuse parenchymal signal loss in the out of phase images which suggest mild hepatic steatosis. No suspicious focal hepatic lesions.No intrahepatic or extra hepatic biliary ductal dilatation.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODESThere is redemonstration of a large retroperitoneal mass which demonstrates heterogeneously increased T2 signal and enhancement extending from the level of the duodenal sweep inferiorly into the upper pelvis, overall increased in size from prior.The component of the mass immediately anterior to the infrarenal aorta at the level of the bifurcation (series 14, image 80) now measures approximately 2.9 x 18 cm, previously 2.7 x 6.4 cm and is now confluent with the previously described additional mass anterior to the left psoas muscle. The previously described partially enhancing nodule anterolateral to the right psoas muscle (series 14, image 91) measures approximately 2.5 x 2.7 cm, previously 1.9 x 2.0 cm.BOWEL, MESENTERY: Postoperative changes from an end to side anastomosis in the descending colon.BONES, SOFT TISSUES: Diastases of the rectus muscles.OTHER: No significant abnormality noted.PELVIS:PROSTATE/SEMINAL VESICLES: Heterogeneously decreased signal within the prostate peripheral zone is nonspecific but could reflect prostatitis.BLADDER: No significant abnormality noted.LYMPH NODES: No pelvic lymphadenopathy.BOWEL, MESENTERY: Post surgical changes in the rectosigmoid colon and tumor extension into the pelvis as described above.BONES, SOFT TISSUES: Fat-containing right inguinal hernia.OTHER: No significant abnormality noted.
Extensive retroperitoneal tumor involvement extending from the level of the duodenal sweep into the upper pelvis, overall increased in size from prior.
