Small bowel anisakiasis is a relatively uncommon disease that results from consumption of raw or insufficiently pickled, salted, smoked, or cooked wild marine fish infected with Anisakis larvae. We report a case of intestinal anisakiasis in a 63-year-old woman presenting with acute onset of abdominal complaints one day after ingestion of raw wild-caught herring from the Northsea. Computed tomography (CT) scanning demonstrated thickening of the distal small bowel wall, mucosa with hyperenhancement, mural stratification, fluid accumulation within dilated small-bowel loops and hyperemia of mesenteric vessels. In patients with a recent history of eating raw marine fish presenting with acute onset of abdominal complaints and CT features of acute small bowel inflammation the possibility of anisakiasis should be considered in the differential diagnosis of acute abdominal syndromes.

Context: Autoimmune pancreatitis is a relatively rare, yet well described cause of chronic pancreatitis. Extrapancreatic findings are now recognized as important manifestations of this entity and viewed as part of a larger disease process tentatively named "IgG4-associated sclerotic disease"., Case Report: We herein report a case of autoimmune pancreatitis with histopathologically proven gastric involvement. We also describe and illustrate the multidetector-row computed tomography appearance of gastric involvement in IgG4-associated sclerotic disease., Conclusion: Autoimmune pancreatitis is increasingly recognized as a multi-systemic disease whose early recognition dramatically affects patient management. Knowledge of the computed tomography appearance of gastric involvement in autoimmune pancreatitis can aid in diagnosis.

Context: PEComas (tumors showing perivascular epithelioid cell differentiation) of the pancreas are exceedingly rare., Case Report: We herein report on a 60-year-old female who noticed a bulge in her right upper quadrant while exercising. Subsequent multidetector-row CT scan showed a 3.5 cm well-defined, encapsulated, hypovascular, solid tumor in the body of the pancreas. Endoscopic ultrasound demonstrated a mixed hypo- and hyper-echoic, well-defined, heterogeneous tumor., Conclusions: Although three pancreatic PEComas (sugar tumors) have been described previously, to the best of our knowledge, this is the first report of a pancreatic PEComa with illustration of its multidetector-row CT and endoscopic ultrasound features in the radiological literature.

Context: Mixed tumors of the pancreas are exceedingly rare., Case Report: We herein report on a 54-year-old female who presented with an enlarging cystic lesion in the head of the pancreas. Right upper quadrant ultrasound and multidetector-row CT scan showed a well-defined unilocular cystic tumor located in the head of the pancreas and surrounded, in part, by a hypervascular solid mass., Conclusion: Although mixed exocrine/endocrine pancreatic tumors have been described previously, to the best of our knowledge, this is the first case of a pancreatic mixed intraductal papillary mucinous neoplasm/endocrine tumor with illustration of its ultrasound and CT features. Moreover, the importance of preoperative analysis of imaging features in the assessment of pancreatic neoplasms is discussed.

This article discusses the rationale behind living (related) donor liver transplantation, the role of imaging in the preoperative evaluation of the potential donor, and the currently available imaging modalities for fulfilling this task. Furthermore, the normal hepatic vascular and biliary anatomy, as seen on imaging, is reviewed and the most common anomalies are highlighted. Finally, critical concepts in the diagnostic evaluation of a donor are discussed with special emphasis on how to accurately measure liver volumes.
