Comparative StudyLumbar spinal cord motion measurement with phase-contrast MR imaging in normal children and in children with spinal lipomas.
We assessed the normal movement of the lumbar spinal cord using phase-contrast MR imaging, and also the movement of the spinal cord in patients with spinal lipoma pre- and postoperatively. Phase-contrast MR imaging proved to be a valuable tool in this context.

Imaging gastrointestinal perforation in pediatric blunt abdominal trauma.
To assess the role of imaging, in particular CT, in the early detection of GI perforation. ⋯ Separating nondisrupting bowel injury from perforation is diagnostically difficult; however, CT remains a good modality for assessing GI perforation in pediatric blunt trauma, but it cannot replace diligent and repeated clinical evaluation of all potential perforation victims.

Multipolypoid intussusceptum: a distinctive appearance of ileoileocolic intussusception at the ileocecal valve.
Objective. To determine whether ileoileocolic intussusception can be diagnosed by a distinctive appearance during pneumatic reduction. Materials and methods. ⋯ In contrast to the ileoileocolic intussusceptums, these intussusceptums were either smoothly marginated (16 patients) or slightly lobular (three patients). Conclusion. In most patients with ileoileocolic intussusception, the intussusceptum has two or more polypoid components at the level of the ileocecal valve which are easily distinguished from the smoothly marginated or slightly lobular intussusceptum seen with ileocolic intussusception.

Case ReportsLocalized Langerhans cell histiocytosis of bone: treatment and follow- up in children.
We report a case of Langerhans cell histiocytosis (LCH) involving the right scapula in a 4-year-old child. Because of progressive shoulder pain and immobility methylprednisolone was injected directly into the lesion under computed tomography (CT) guidance. ⋯ We consider intralesional corticoid instillation a safe method when performed under CT guidance. For initial evaluation and follow-up, MRI and US yielded reliable results in comparison to plain films and CT, thus helping to reduce the radiation dosage in children.

Case Reports Meta AnalysisLymphatic air embolism: a new hypothesis regarding the pathogenesis of neonatal systemic air embolism.
Objective. Neonatal systemic air embolism (NSAE) has been thought to result from introduction of air into the pulmonary veins through hypothesized alveolar-capillary fistula. The objective of this paper is to reassess the distribution of intravascular air visualized radiographically in this entity. ⋯ PIE was found to be a very common associated finding in NSAE. Based on our current knowledge of pulmonary lymphatics, radiographic anatomy, and the lymphatic location of PIE, we propose that air within the pulmonary lymphatic system (PIE) gains access to the systemic venous system via lymphatic ducts, which results in the clinical entity NSAE. This readily explains the venous predominance of air in NSAE.
