Reason: Retroperitoneal Sarcoma. S/p XRT, needs restaging MRI. Some question of IVC involvement ABDOMEN:LIVER, BILIARY TRACT: Right hepatic T2 hyperintensity, likely a cyst.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES:Retroperitoneal mass centered within the IVC is compatible with a leiomyosarcoma and has significantly decreased in size from the prior exam with decreased enhancement. There is a rim enhancing infrarenal component which measures 3.1 x 2.5 cm (12/33), previously 4.4 x 4.3 cm. There may be some extension to the right psoas musculature, similar to the prior exam. And nonenhancing intraluminal component extending superiorly, expanding IVC, is similar in size. There is a rim of nonenhancing thrombus extending inferiorly, similar in distribution to the prior exam.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.PELVIS:UTERUS, ADNEXA: No significant abnormality noted.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Diverticulosis without evidence of diverticulitis.BONES, SOFT TISSUES: Scoliosis and degenerative changes.OTHER: No significant abnormality noted.
1.Leiomyosarcoma within the IVC has significantly decreased in size from the prior exam with decreased enhancement also seen.2.No evidence of metastatic disease.
