Upper abdominal CT Scan, Lymphoma.CT ABDOMEN WITH CONTRAST- Cancer Non-Hodgekins Lymphoma confirmed. Indication- Epigastric pain. History- Breast ca and mastectomy. Findings- Bilateral breast prostheses are noted. There is no pericardial or pleural fluid. The lung bases are unremarkable. The osseous structures demonstrate a scoliosis but no suspicious lytic or blastic lesions are identified. Abnormal ill-defined soft tissue density is seen infiltrating the epigastric region encasing the portal vein, and left renal vein. This most likely represents adenopathy. A large mantle of adenopathy on image #26 measures 4cm x 4.4cm and is centered in the porta hepatis region. Probable adenopathy is also seen just superior to the pancreatic body as well as in the gastrohepatic ligament. There are no focal intrahepatic lesions identified. There has been prior cholecystectomy with associated prominence of the common bile duct, likely relating to the prior cholecystectomy. The adrenal glands and kidneys and spleen are unremarkable. No free fluid or free air or inflammatory bowel wall changes. On image #40, there is a 6mm abnormal soft tissue density nodule seen in the anterior peritoneal cavity adjacent a loop of colon. This is of uncertain clinical significance. There is a similar appearing small nodule seen measuring 5mm in size just anterior to the superior tip of the right iliac wing. A smaller similar appearing nodule is seen more inferiorly within the right iliac fossa measuring only 2mm in size. IMPRESSION- 1. Abnormal epigastric adenopathy. There is a nonspecific appearance. The appearance alone would suggest lymphadenopathy associated to lymphoma, but given the history of breast cancer, metastatic adenopathy cannot be excluded. Several prominent retrocrural lymph nodes are also noted and likely associated with the same process. 2. There are several small peritoneal sub-cm nodules that are suspicious for adenopathy but less pronounced in size when compared to the epigastric process.
