[Sports injuries in children and adolescents].

Clinical/methodological Issue: Due to active participation of children and adolescents in school sports as well as in club sports, sporting injuries in childhood are common. Because skeletal maturity is not yet complete, injury patterns in children differ from sporting injuries in adults. Knowledge of the pathophysiologic characteristics, as well as knowledge of typical injury sequelae, is of great relevance to radiologists.

Case Report: 7-Year-Old Boy with Incarcerated Internal Hernia Leading to Extensive Intestinal Necrosis Due to a Large Congenital Mesenteric Defect.

We present a case of a 7-year-old boy with acute abdominal symptoms initially misdiagnosed as constipation. Delayed imaging diagnostics revealed an ileus with contorted small intestine, so laparotomy was indicated. An acute bowel obstruction was found based on an incarcerated internal hernia.

Intraductal papillary mucinous neoplasms of the pancreas: radiological predictors of malignant transformation and the introduction of bile duct dilation to current guidelines.

Objective: To evaluate the current guidelines as a model to predict malignancy and to determine further radiological predictors of malignancy in intraductal papillary mucinous neoplasms (IPMNs).

Methods: 384 patients who had undergone a pancreatic operation with the pathological diagnosis of IPMN as well as applicable pre-operative imaging (CT/MRI) were included in the study. Images were evaluated retrospectively in consensus by two radiologists, using a standardized checklist.
