Massive retroperitoneal sarcoma resection 12/2012. 12/1/2015 MR demonstrate increased enhancement in the right retroperitoneum recess adjacent to the right diaphragmatic crus. ABDOMEN:LIVER, BILIARY TRACT: No significant abnormality noted.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Status post right nephrectomy.RETROPERITONEUM, LYMPH NODES: The soft tissue lesion adjacent to the right diaphragmatic crus measures approximately 2.2 x 1.2 cm (series 14/58), compared to 2.5 x 1.1 cm previously. The lesion measures approximately 3.0 cm in the craniocaudal dimension.The previously seen nodule lateral to the above stated lesion adjacent to the liver is no longer visualized and may have represented averaging from an adjacent colonic diverticula.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Stable small cardiophrenic angle lymph nodes.
Relatively stable enhancing right retroperitoneal soft tissue adjacent to the right diaphragmatic crus, remains suspicious for recurrent disease and continued surveillance imaging is recommended. The previously seen nodule lateral to this lesion adjacent to the liver is no longer visualized.
