Autoimmune pancreatitis (AIP) is rarely associated with pancreatic pseudocysts. AIP-associated pseudocysts requiring drainage despite steroid therapy are rather rare. We report a case of AIP with an infected pseudocyst requiring drainage despite steroid therapy. A 68-year-old male was diagnosed with AIP via pancreatic imaging, a high serum immunoglobulin G4 level, and steroid responsiveness. The AIP was accompanied by a pancreatic pseudocyst. Steroid therapy was prescribed, but the pancreatic pseudocyst became aggravated during steroid tapering. Endoscopic ultrasonography-guided cyst drainage was required; the pseudocyst then became completely resolved.

Pancreatic pseudocyst rupture into the portal vein is a very rare complication and only three reported cases were confirmed using MRI. We report the case of a 50-year-old man with fistula formation between the pseudocyst and the portal vein, confirmed noninvasively by MRI. T2-weighted MR images and magnetic resonance cholangiopancreatography showed fluid signal intensity within the portal, superior mesenteric, and splenic veins, and a direct communication between the pseudocyst and the portal vein.

Enteric duplications associated with the pancreas are especially uncommon, and the differential diagnosis of pancreatic duplication cysts is often difficult, and may be confused with various cystic lesions of the pancreas. We report a case of pancreatic duplication cyst; present the images and laboratory findings including cyst fluid tumor markers. MR and MRS findings enabled the detection of the location, contour, characteristics of cystic fluid and definition of tissue planes between the lesion and adjacent structures, providing useful information for an accurate surgical approach.

A pancreatic pseudocyst with a mediastinal extension is a rare clinical entity. Intrathoracic symptoms such as dysphagia or dyspnea due to compression or associated pleural effusions are quite common. The pseudocysts transverse the diaphragm via the esophageal hiatus or aortic hiatus or by eroding directly through the diaphragm. Here, we report a case of a pancreatic pseudocyst with a mediastinal extension presenting as dysphagia and dyspnea. The diagnosis was confirmed by computerized axial tomography of the chest and abdomen. Usually, the proper management of a large pseudocyst includes percutaneous or surgical internal drainage, but in this case the mediastinal components disappeared with conservative medical treatment.

Effusions arising from acute pancreatitis are usually small, left sided and self limiting. The incidence of pleural effusions in acute pancreatitis is reported between 3% and 17%. In chronic pancreatitis, as a consequence of fistula and pancreatitic pseudocyst formation or by spontaneous rupture of a pancreatic psudocyst directly into thoracic cavity, extremely large effusions may be seen. When the underlying pacreatic disease is asymptomatic, the diagnosis is made by measuring the amylase content of the pleural fluid. We experience a case of left sided pleural effusions caused by pancreatico-pleural fistula associated with pancreatic pseudocyst. The diagnosis was made by measuring of pleural fluid amylase level(80000U/L). Abdominal CT scan revealed pancreatic pseudocyct and pancreatitis with extension to left pleural space through esophageal hiatus and extension to left subdiaphragmatic space. Left pleural effusions were decreased after fasting, total parenteral nutrition and percutaneous pleural fluid catheter drainage. We reported a case of pleural effusions and pacreatico-pleural fistula asssociated with asymptomatic pancreatic disease with review of literatures.

Purpose : Magnetic resonance cholangiopancreatography(MRCP) is a noninvasive method for imaging the pancreaticobiliary tree. The aim of this study was to evalute the usefulness of MRCP for the diagnosis of pancreaticobiliary diseases in children. Methods : From October 1996 to May 2001, 67 patients with obstructive jaundice and three patients with chronic recurrent pancreatitis were evaluated with abdominal ultrasonography and MRCP. The final diagnosis was based on the operative and pathologic findings with biopsy specimen including clinical and laboratory findings. Results : A total of 70 patients, consisting of 31 males and 39 females, with a mean age of $2.6{\pm}3.3$ years were studied. The final diagnosis was biliary atresia in 25, neonatal cholestasis in 18, choledochal cyst without anomalous pancreatobiliary duct union(APBDU) in nine, choledochal cyst with APBDU in seven, cholestatic hepatitis in five, chronic recurrent pancreatitis in three, sclerosing cholangitis in two, and secondary biliary cirrhosis in one case. The overall diagnostic accuracy of abdominal ultrasonography was 75.7% and that of MRCP was 97.1%. The sensitivity and specificity of MRCP were 100% and 98% for biliary atresia, 87.5% and 100% for choledochal cyst with APBDU, 100% and 100% for choledochal cyst without APBDU, sclerosing cholangitis and chronic recurrent pancreatitis, respectively. Conclusion : MRCP is a fast, non-invasive and reliable method for diagnosing pancreaticobiliary diseases in children and will be the standard diagnostic procedure in the future.

An 8-year-old boy presented with abdominal pain and poor oral intake for two months. Serum amylase and lipase levels were elevated. CT of the abdomen and chest X-ray showed two pseudocysts at the pancreatic uncinate process, pancreatitis with a parenchymal defect, a large amount of ascites, and a right pleural effusion. MR cholangiography and endoscopic retrograde cholangiopanreaticography revealed a pancreatic duct disruption. The patient was successfully treated with a chest tube placement and percutaneous drainage. After surgery, his general condition improved; the serum level of amylase normalized and the pleural effusion resolved. Pancreatic injuries are rare in pediatric blunt trauma; however, diagnostic difficulty is common with isolated blunt trauma. Therefore, a high index of suspicion should follow such an injury. We report the case of an 8-year-old boy with pancreas transection, ductal disruption, ascites, and pleural effusion who was successfully treated.

Ciliated foregut cyst is a relatively rare disease; thus, most reports are in the form of case studies. This benign cyst is usually found in the mediastinum and account for approximately 20% of all mediastinal masses. However, it is rarely found in the hepatobiliary and peripancreatic regions. Approximately 20 cases of ciliated foregut cysts involving the pancreas have been reported in the Enlgish literature. Here, we present a case of ciliated foregut cyst that occurred in the tail of the pancreas in a 29-year-old female. The patient's ultrasonography, CT, and MRI findings are presented, along with a review of the literature.

Purpose : To evaluate the usefulness of MRCP in the diagnosis of the variable causes of common bile duct(CBD) dilatation, except stone or tumor Materials and methods : Twenty-six patients(M:F=15:11, mean age; 62 years) with both MRCP and ERCP were included in this study. Dynamic MRCP(n=12) and contrast-enhanced MRI(n=10) of abdomen were also added. Dilatation of CBD, intrahepatic ducts and pancreatic duct was evaluated, including coexistence of intrahepatic ductal stone, pancreatic pseudocyst, and papillary or papillary edema. The criteria of CBD dilatation was over than 7mm(n= 21, without cholecystectomy) or 10 mm(n=5, with cholecystecto-my) in diameter on T2-weighted coronal image. Results : The mean diameter of CBD was 12.7mm without cholecystectomy(9-19 mm) and 13.0 mm with cholecystectomy(10-15mm), respectively(p 〉0.05). Cholangitis(n=11, 42.3%), chronic pancreatitis(n=8, 30.8%), stenosis of distal CBD(n= 6, 23.1%), periampullary diverticulum(n=3, 11.5%), stenosis of ampulla of Vater(n=2, 7.7%), dysfunction of sphincter of Oddi(n=2, 7.7%), acute focal pancreatitis in the pancreatic head(n=2, 7.7%), papillitis(n=1, 3.8%), pseudocyst in the pancre atic head(n = 1, 3.8%), and ascaris in CBD(n=1, 3.8%) were noted. Pancreatic duct dilatation(n=10, 38.5%) and duodenal diverticulum(n=3, 11.5%) were also seen on MRC P. On dynamic MRCP(12 patients), distal CBD was visualized in 2 patients(16.7%), which was not shown on routine MRCP. Only 1 patient(10.0%) showed papillitis with slightly enhancing papilla on contrast-enhanced MRI (10 patients). Conclusion : MRCP was thought to be helpful in the evaluation of the causes of CBD dilatation, not caused by stone or tumor, especially in the cases of stenosis of distal CBD and chronic pancreatitis, dysfunction of sphincter of Oddi on dynamic MRCP and cholangitis and pericholangitic abnormality on contrast-enhanced MRI.
