Solitary bone cyst in the infant radius. A case report.

The exceptional case in the distal radius of an 18-month-old girl demonstrates the natural history and characteristic features of solitary bone cyst at an early age. There were recurrent pathological fractures and even recurrence of the cyst, but spontaneous complete healing occurred after a period of 7 years. Splinting of the fractures, curettage and bone graft were performed per primum. Aspiration of the cyst and collapse of the cyst walls were secondary procedures. The recommended treatment is biopsy and prolonged immobilization until spontaneous healing of the cyst is complete.
