Аннотация
OBJECTIVE: To demonstrate imaging findings during the follow-up of patients with aneurysmal bone cyst (ABC) of C2 treated with intralesional injection of calcitonin and methylprednisolone.
METHOD: Three patients with ABC of C2 were treated percutaneously with intralesional injection of calcitonin and methylprednisolone. All the patients were females, with ages varying from 6 to 13 years. All of them presented with cervical masses, but without neurological symptoms.
RESULTS: Imaging follow-up with CT and plain films showed progressive ossification and reduction of the blood-filled cavities with volume reduction of all lesions. No recurrence was noted during the follow-up.
CONCLUSION: Intralesional injection of calcitonin and methylprednisolone is a safe treatment option for cervical ABC. The CT scan is especially valuable as a guide of injection site and for the follow-up of ossification of the treated ABCs.
