A case of acinar cell carcinoma of the pancreas that formed extensive tumor thrombus of the portal vein

Abstract: A 58-year-old man was admitted to our hospital because of anorexia and back pain. He had been previously diagnosed with chronic pancreatitis with blood thrombus of the splenic vein at another hospital. Abdominal ultrasonography and computed tomography revealed a large mass in the body and tail of the pancreas, which directly invaded the stomach and the spleen. Small nodular metastases in both lungs were also detected. Furthermore, tumor thrombus continuously involved the splenic and proximal superior mesenteri… Show more

“…There have been only a few case reports of ACC accompanying tumor thrombus in the portal vein, superior mesenteric vein, and splenic vein. [ 3 , 6 , 7 , 29 , 37 , 38 ] It is important to differentiate tumor thrombus from blood thrombus because therapeutic strategy and prognosis varies. In our case, although we could not obtain tissue from the tumor in the portal vein, the compatible FDG uptake of the thrombus with the primary tumor, and the contiguous nature of the extension from the pancreatic primary tumor support the conclusion of tumor thrombus.…”

“…However, intrinsic venous obstruction by tumor thrombus, while a common occurrence in hepatocellular carcinoma, rarely occurs in pancreatic cancer [16]. Indeed, there have been only a few cases of pancreatic cancer with portal vein tumor thrombus, including two cases of ACC accompanied by tumor thrombus [15, 16]. Furthermore, distinguishing tumor thrombus from a blood clot is very important, because it is well recognized that a tumor thrombus involving the mesenteric venous system is associated with liver metastases.…”
