PDFAbstract
Objective To study imaging and pathological findings of enchondromas in children. Methods 12 enchondromas of imaging feature were retrospectively reviewed. Imaging evaluation included the assessment of lesion size, location to the growth plate, mineralization matrix, periosteal reaction, MR signal characteristics, and intraosseous and soft-tissue edema. Results Lesions located in the phalanx, metacarpal, femur, tibia take account for 33%, 25%, 33% and 8% respectively. Matrix mineralization in typical "ringsand-arcs" pattern was observed in 20% of the lesions with radiography/CT. Lesions were expansive with endosteal scalloping in 75% of cases and 50% of them were close to growth plate. All enchondromas in MR imaging demonstrated as typical cartilaginous matrix of lobules with high T2 signal, low T1 signal, and peripheral enhancement. Conclusion Enchondroma in children are relatively rare tumors, with frequent endosteal scalloping and rare matrix mineralization.
