We presented two cases of aneurysmal bone cyst; one case in the second lumbar vertebra and the other case in the second cervical vertebra.Case 1: a 15-year-old manHis chief complaint was low back pain. CT showed a expanded and destructive mass lesion from the transverse process to body of L2. After curettage of the lesion and bone grafting in the involved area of the vertebral body, a posteroeateral fusion was done. At 5 months following the operation, the patient had no recurrence showing a solid bony fusion on the roentgenograms.Case 2: a 20-year-old womanHer chief complaint was swelling of the posterior region of neck and severe pain referred to the left shoulder. Roentgenograms revealed a spherical tumor surrounded with a thin bone-shell. The tumor was resected and a left laminectomy of C2 was performed. Roentgenograms and CT showed no recurrence at 15 year after the operation. She was free of complaints.
