Stress injuries occur when normal bone is subjected to chronic and repeated mechanical loading.<b> </b>Children are at particularly increased risk for these types of injuries compared to adults, due to weaker chondro-osseous junctions, increased physical activity, less muscle mass, narrower bones with thinner cortices, hormonal changes, and decreased mineral content of bones. Pediatric stress injuries consist of physeal and apophyseal stress injuries and stress fractures. When the primary physes of the long bones sustain repetitive workloads, endochondral ossification is impeded, and unmineralized cartilage extends into the metaphysis. Such repetitive workloads also affect associated apophyses, leading to chondrocyte proliferation, hypertrophy, and inflammation. Stress fractures, also known as fatigue fractures, occur when bone remodeling is given insufficient time to repair “micro-trauma” damage and additional mechanical loading cycles enable damage to accumulate in the bone, ultimately leading to a fracture. This educational exhibit will review the imaging findings associated with stress injuries of the axial and appendicular skeleton commonly seen in older children and adolescents. The exhibit will draw on case examples of children participating in a wide range of activities to illustrate the range of stress injuries in the pediatric population and their diagnostic findings, including cheerleading, dancing, baseball pitching, climbing, and even bowling and competitive yoga.

Cecostomy tubes are not uncommonly encountered in a busy pediatric radiology practice but can pose a challenge to the unfamiliar. These devices provide access to the colon for routine antegrade enemas to promote bowel regularity and continence, most commonly in children with spinal dysraphism. This educational exhibit will describe the typical routine for cecostomy tube exchange, characterized by the Seldinger technique, and describe interesting cases of more difficult exchanges and complications, including different scenarios of broken and malpositioned tubes, and a practical approach to management of these challenges. After viewing this exhibit, the radiologist should be armed with several strategies for approaching both routine and complicated cecostomy tube exchanges. Read More

Fat, like any other organ or tissue, can cause both disease and symptomatology. In the pediatric abdomen and pelvis, fat may be involved by a number of conditions, ranging from symptomatic to occult, self-limited to progressive, benign to malignant. This is a review of multimodality cross-sectional imaging findings associated with abdominopelvic fat pathology in children. Read More

Renal trauma is not uncommon in the pediatric population and can be seen in a wide variety of settings, from minor sports-related injuries to serious motor vehicle accidents. The imaging appearance is as varied as the etiology of injuries, ranging from minor parenchymal defects to avulsion of the vascular pedicle. Our educational poster aims at exploring a variety of injuries of the kidney in children, including chronic subcapsular hematoma, different severities of laceration, renal rupture without and with urine extravasation, injuries to the ureter, trauma involving kidneys with congenital anomalies, and trauma in an undiagnosed Wilms' tumor. Because renal trauma can present with many different faces, we aim to highlight essential diagnostic pearls as well as some unusual factors which may predispose the kidney to injury. Read More
