At EOB-enhanced hepatic dynamic MRI, the test-injection method yielded better image quality of hypervascular HCC and improved adequacy of timing of HAP.
While pneumatosis intestinalis (PI) is a rare condition associated with a wide variety of underlying diseases, PI with intraperitoneal free air and ascites is extremely uncommon and is difficult to distinguish from diffuse peritonitis. We herein describe the case of an 87-year-old male who was admitted to our hospital with abdominal pain, distension and nausea. Abdominal plain radiography and computed tomography revealed intramural air collection in the entire intestine, intraperitoneal free air and ascites. Although we first suspected bowel necrosis and perforation, his physical findings and the properties of the diagnostic abdominal paracentesis did not support this diagnosis. Therefore, we selected conservative management, and the intramural air, intraperitoneal free air and ascites disappeared 1 week later. Recognition of the possible presence of non-surgical PI and intraperitoneal free air, although it is extremely rare, is important to avoid a misdiagnosis and the associated unnecessary surgical intervention.
A 79-year-old female was transferred to our hospital because of suspicion that her acute pancreatitis was caused by stone impaction in the common bile duct (CBD). Laboratory examination showed aspartate aminotransferase, 1645 U/l; alanine aminotransferase, 476 U/l; amylase, 1365 U/l; and white blood cells, 10700/μl. Computed tomography (CT) showed an enhanced tumor in the neck of the gallbladder, an abnormal CBD filled with a high-density area, and localized swelling in the head of the pancreas. Magnetic resonance cholangiopancreatography also showed a low-intensity area in the CBD. Endoscopic retrograde cholangiopancreatography showed coagulated blood discharged from the papilla of Vater. The diagnosis was acute pancreatitis caused by impaction of coagulated blood from a gallbladder tumor. A curative operation was performed 10 days after endoscopic bile duct drainage. Gallbladder cancer (GBCa) has no special symptoms and is usually diagnosed at an advanced stage; however, hemobilia and acute pancreatitis are unusual as an initial presentation of GBCa.
Acute gastric volvulus is a torsion of the stomach by more than 180° and a life-threatening condition. We present a 50-year-old male patient with acute abdominal pain who has Down syndrome/trisomy 21. Computed tomography showed a significant distended stomach with features of a severe gastric volvulus. Emergency operation in form of reduction and gastropexy was performed. We are not aware of any similar cases published in the English literature, where as gastric volvulus occurred in a patient with Down syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
