Soccer practice is steadily increasing in the world and brings its statistics of injuries, most of them acute and minor. There is a better understanding of the epidemiology and biomechanics in the genesis of such injuries. This electronic presentation on soccer injuries in children outlines the following: 1. Review of epidemiology and biomechanics factors (equipment, athletic skills, contact sport). 2. Mechanisms of injury: headings, avulsion, contusion, fracture, twisting knee injury, overuse). 3. Imaging characteristics at various sites of injury. Read More

Neuroblastoma (NBL) is the most common extracranial solid malignancy of childhood. Biological features are known to affect disease severity. Status of amplification of the MYCN proto-oncogene is among several factors that affect the prognosis. CT texture analysis of tumor provides a step from qualitative to quantitative assessment, with the added bonus of use of routinely acquired images without the need for further tests. The aim of the study is to ascertain the ability to differentiate between MYCN-amplified and non MYCN-amplified neuroblastoma on pre-treatment CT images. The hypothesis is that lesion microenvironment and heterogeneity may differ significantly between MYCN-amplified and non MYCN-amplified tumor. Such differences may be exhibited in first-order texture analysis techniques that could detect more subtle differences in tumor heterogeneity by quantifying both pixel attenuation. This retrospective study objective is to explore the correlation between the first –order CT texture analysis (CTTA) and MYCN amplification status of neuroblastoma. Read More

Congenital prepubic sinus is a rare congenital anomaly of the urinary tract and is clinically active by discharge from a skin opening overlying the symphysis pubis. Its etiology is still unclear, and a variant of dorsal duplication of the urethra is the favored theory. It has been reported in males as well as in females. Its size and extent are variable, starting from prepubic area extending toward the bladder or urethra and may have a blind end.. This report is about the imaging approach in a series of 5 cases with similar clinical signs of presentation. Read More

Pediatric liver transplant (PLT) is an established treatment for many hepatic conditions in children. In recent years there has been a significant increase in the number of PTL associated with an improved survival. In children however, due to the complex surgical procedures and peculiar hemodynamic physiology there is also an increased risk for vascular and biliary complications. High resolution ultrasonography (US) is the modality of choice to evaluate and monitor the evolution of pediatric liver graft. This exhibit intends to illustrate fellows and residents with the US characteristics of the normal hepatic anatomy, the normal early and late US appearances of the graft, and the US features of complications that may compromise graft’s survival.
