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.\u2002\u2002Conclusion: 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.<\/jats:p>","DOI":"10.1590\/s0004-282x2008000500020","type":"journal-article","created":{"date-parts":[[2008,10,22]],"date-time":"2008-10-22T15:02:43Z","timestamp":1224687763000},"page":"711-715","source":"Crossref","is-referenced-by-count":16,"title":["Aneurysmal
