A 3-year-old boy with osteogenesis imperfecta had hyperplastic callus formation in the right femur, without preceding trauma or fracture. Radiologically, this bony mass in the femoral shaft mimicked osteosarcoma. Open biopsy showed that it was benign and suggested hyperplastic callus formation. Seven months after the biopsy, the hyperplastic callus had practically vanished. A similar process developed in the left femur 1 year later, also without fracture.
一名患有成骨不全症的3岁男孩右侧股骨出现了增生性骨痂形成，之前并无外伤或骨折史。在放射学上，股骨干的这个骨质肿块类似骨肉瘤。切开活检显示其为良性，提示为增生性骨痂形成。活检七个月后，增生性骨痂几乎消失。一年后，左侧股骨也出现了类似过程，同样没有骨折。
