Lobulated heterogeneous mass in the pancreatic tail growing into and obstructing the colon at the splenic flexure. Mass also invades the left renal vein and upper pole calyx, resulting in delayed left nephrogram. Splenic vein is also obstructed with short gastric varices. Numerous metastases throughout the left hepatic lobe. Possible small pulmonary embolus in a subsegmental right lower lobe artery (first image). Small nodules in the imaged lower lobes are worrisome for metastases.
