Aneurysmal bone cysts (ABC) arising from the cervical spine in children is relatively rare. Two cases with aneurysmal bone cysts arising from the cervical spine were successfully operated on in order to achieve radical tumor resection and reconstruction cervical spine stability were reported.Case1: A five year-old boy with neck pain and limitation of cervical movements. Clinical and histological investigation revealed ABC at the body of C4. Extensive curettage and bone grafting from C3 to C5 spine were carried out. Complete bony union was achieved. At six years follw-up, no tumor recurrence was seen, the spinal canal had normal growth and the patient had returned to normal activity.Case 2: A twelve year-old girl. Radiological examination and histological findings revealed ABC extensively occupying the body and lamina of C4. Staged resection and reconstruction were done. In the first stage, wide curettage through the posterior approach followed by bone grafting with Luque instrumentation were done. Two weeks later extensive curettage of the C4 lesion, cervical interbody fusion with bone grafting and plating from C3 to C5 were carried out. At three years follow-up, complete bony union was observed with no recurrence of the lesion, nor any disturbance of spinal canal growth.
