Case ReportsIngestion of magnetic foreign bodies causing multiple bowel perforations.
We report a 3-year-old boy who presented to the emergency room with the suspicion of having swallowed an unknown number of industrial metallic objects, subsequently shown to be magnets. During the hospital course, the boy developed multiple bowel perforations caused by the swallowed magnets that were attracted across the bowel walls. ⋯ By this report we aim to alert the radiological and pediatric community to the possible presentation of multiple magnet ingestion. If multiple magnets or a combination of magnets and metallic objects are suspected, immediate radiographic evaluation is warranted for confirmation, and urgent surgical exploration may be necessary to prevent bowel perforation and/or intraabdominal abscess formation.

ReviewDiffusion-weighted and diffusion tensor imaging for pediatric musculoskeletal disorders.
Diffusion-weighted imaging (DWI) is a powerful tool that has recently been applied to evaluate several pediatric musculoskeletal disorders. DWI probes abnormalities of tissue structure by detecting microscopic changes in water mobility that develop when disease alters the organization of normal tissue. ⋯ This article focuses on the current and future applications of DWI in the musculoskeletal system, with particular attention paid to pediatric disorders. Although most of the applications are experimental, we have emphasized the current state of knowledge and the main research questions that need to be investigated.

Our objective was to assess the utility of PET-CT in five pediatric patients with Langerhans cell histiocytosis (LCH) who underwent PET-CT imaging for clinical staging and determination of lesion activity at various stages of treatment and follow-up. PET-CT combines the anatomic detail of CT and the physiologic activity of (18)F-FDG imaging. We conclude that PET-CT information is clinically useful to evaluate disease activity and response to therapy and provides information that cannot be obtained from technetium 99m methylene diphosphonate bone scans or radiographs.
