RADIOLOGY: ABDOMEN: Case# 33492: SARCOMATOSIS PERITONEUM. The patient is a 64 year old female. 1. Multiple heterogeneous low attenuation lesions with irregular enhancement are seen throughout the abdomen, the appearance is that of diffuse metastatic disease. There is effacement of liver parenchyma and possible extension into the liver from the adjacent masses. Multiple sites of metastatic disease are seen within mesentery as well as the lower pelvis. The right kidney is displaced inferiorly by the large mass adjacent to the right lobe of liver extending inferiorly. Cannot rule out direct invasion of the kidney. The right renal pelvis is dilated, but there is no calyceal dilatation. The enhancement of the right kidney appears unusual but this may be due to volume averaging of the cortex of this displaced right kidney. A soft tissue implant in the subcutaneous tissues of the left lower quadrant, as well as abnormal soft tissue in the region of the vaginal entroitus with infiltrative stranding into the adjacent perineal fat suspicious for metastasis. 2. The lung bases are clear, there is no definite evidence of bony metastases on review of bone windows. 3. Status-post splenectomy.
