Cystic Lesions in the Stomach

Cystic lesions of the stomach are rare and usually detected incidentally during surgery or autopsy. Amongseven cases of cystic masses, duplication cysts accounted for four, retension cysts of ectopic pancreas for two,and cystic lymphangioma remaining one. In the upper gastrointestinal series, all were submucosally, whileendoscopic ultrasonography showed that the location of cystic masses was also submucosal. Except for two cases ofduplication cyst and cystic lymphangioma which were thin-walled, lesions were well-defined and showed lowattenuation. In addition, abdominal CT scanning showed two cases of retension cyst of ectopic pancreas.

A Case of Obstructive Jaundice Caused by Cavernous Transformation of the Portal Vein / 대한소화기내시경학회지

Cavernous transformation of the portal vein is a rare condition probably arising secondary to extrahepatic portal vein thrombosis or obstruction with recannalization and/or collateral veins formation to bypass the obstruction. It is believed that cavernous transformation of the portal vein is caused by a variety of diseases associated with periportal collateral development and hepatopedal flow. It is known that portal vein occlusion, which is the actual cause of cavernous transformation, has a wide variety of etiologies, such as congenital abnormalities, omphalitis, pancreatitis, various carcinoma, and liver cirrhosis. In most cases, the revealing symptom is upper gastrointestinal bleeding. Rarely, however, diagnosis is made from obstructive jaundice. Extensive collateral veins due to portal vein occlusion may compress and narrow the biliary tract. A 39-year-old man was admitted due to jaundice and abdominal discomfort for 1 month. He was confirmed to have obstructive jaundice due to collateral vessels of cavernous transformation of the portal vein. We report a case of obstructive jaundice caused by cavernous transformation of the portal vein.
