    Notes: Abstract: Celiac axis stenosis is frequently associated with pancreaticoduodenal artery aneurysms. Although the cause of stenosis was not clear in most of the reported cases, compression of the median arcuate ligament of the diaphragm was found to be responsible for the stenosis in 7 of 42 reported cases of this type of aneurysm. We report a case of aneurysm caused by compression of the median arcuate ligament of the diaphragm and celiac plexus. An asymptomatic 43-year-old Japanese man was admitted with a low echoic lesion in the uncus of pancreas. Computed tomographic scan and angiogram revealed stenosis of the celiac axis and two aneurysms in the inferior posterior pancreaticoduodenal artery. The celiac plexus and median arcuate ligament were divided surgically and normal flow was reestablished in the celiac axis. One of the aneurysms was resected and the afferent artery of the other aneurysm was ligated. In the setting of pancreaticoduodenal artery aneurysm associated with celiac axis stenosis, management of stenosis should be considered in addition to local treatment of the aneurysm. In this context, division of median arcuate ligament and celiac plexus or aorto-celiac bypass may normalize the flows in the pancreaticoduodenal arcade and could be effective in preventing aneurysm reformation.

    Notes: Abstract A case of extensive extra-and intrahepatic portal tumor thrombosis, with no metastatic foci in liver parenchyma, secondary to advanced gastric carcinoma in a 69-year-old man is reported. The portal tumor thrombosis was characterized by enlargement of the thrombosed segment of the vein, decreased density mass without intraluminal enhancement of the involved vein, nonvisualization of the portal venous branch in the involved lobe, and the so-called cavernous transformation of the portal vein. The surgically resected gastric specimen showed Borrmann type 3 advanced papillary adenocarcinoma. The portal tumor thrombus is presumed to have arisen from vascular invasion in the primary foci of gastric carcinoma, and then to have permeated the portal vein without invasion of liver parenchyma.
