Almost 20% of asymptomatic children and adolescents had benign bone tumors of the extremities, a review of a longitudinal radiographic collection showed.
Overall, 35 benign tumors were identified in 33 pediatric patients whose median age was 8. The most commonly identified tumor types were non-ossifying fibromas (NOF, 7.5%), enostoses (5.2%), osteochondromas (4.5%), and enchondromas (1.8%).
The findings came from a review of the Brush Inquiry, a collection of 25,555 radiographs and 262 healthy children. The x-rays were all left-sided views of each patient’s upper and lower extremities. The overall incidence of benign tumors in the asymptomatic population was 18.9%, and the median age at detection after a previous negative radiograph was 9 years. NOFs were the only tumor type that resolved over time, Christopher D. Collier, MD, of the University of Chicago, reported during the Musculoskeletal Tumor Society (MSTS) virtual meeting.
“The goal of this study was to give us
