Intrahepatic Cerebrospinal Fluid Pseudocyst: A Case Report and Systematic Review.

BACKGROUND: Perforation of a solid visceral organ and subsequent development of a cerebrospinal fluid pseudocyst is a rare complication of ventriculoperitoneal shunts. CASE DESCRIPTION: A patient with a history of global developmental delay presented with shunt failure secondary to an intrahepatic cerebrospinal fluid pseudocyst. The diagnosis had not been initially apparent owing to the absence of ventriculomegaly or a palpable abdominal mass and/or tenderness. Following diagnosis on abdominal imaging, the pseudocyst was aspirated, and the ventriculoperitoneal shunt was successfully revised. CONCLUSIONS: A series of 22 cases of previously reported intrahepatic pseudocysts and abscesses is presented, and the putative mechanisms that have been put forward to explain the development of these collections are discussed. Review of the literature demonstrates that several techniques have been successfully employed in the management of this complication.

Intrahepatic Pancreatic Pseudocyst Complicated by Pancreatitis: A Case Report.

Pancreatic pseudocyst is a common complication of acute pancreatitis. Pseudocysts are commonly observed in the lesser sac and retroperitoneum; they are rarely seen in the liver. Herein, we report a case of intrahepatic pseudocyst, complicated by asymptomatic groove pancreatitis, that has successfully been treated with hepatic resection. A 70-year-old woman was referred to our hospital with severe upper abdominal pain. Abdominal computed tomography scan showed 11x10 cm sized cystic lesion in the left lateral section of the liver. Appearance of the pancreas was relatively normal. Endoscopic aspiration revealed a high level of amylase in the cystic fluid. After endoscopy, signs of peritonitis were observed; then, a left hemihepatectomy was performed. Pathologic examination revealed an intrahepatic pancreatic pseudocyst. The presence of intrahepatic cystic lesion in patients with suspected pancreatitis should raise the suspicion of intrahepatic pseudocyst. Intrahepatic pancreatic pseudocysts may be the only clinical manifestation even without an episode of acute pancreatitis.

A Case of Intrahepatic Pseudocyst Complicating Acute Pancreatitis / 대한소화기학회지

Although most of pseudocysts as one of complications of pancreatitis occur primarily within the pancreas, the extrapancreatic locations of pseudocysts, especially in the liver, are rare events. With advanced technology of imaging studies including abdominal computed tomography, ultrasonography, and magnetic resonance imaging, their frequency seems to be increasing. We report here a case of left intrahepatic pancreatic pseudocyst following acute pancreatitis. Percutaneous puncture revealed a high level of amylase and lipase in the collection, confirming the diagnosis of intrahepatic pseudocyst. Symptomatic intrahepatic pseudocysts can be managed surgically, transcutaneously or endoscopically, and asymptomatic intrahepatic pseudocysts can be treated conservatively. We report this case with a review of literature.
