Vertebral tumors of the spine have a very low frequency. The incidence of aneurysmal bone cyst (ABC) ranges between 1% and 4% of all tumors. Its predominant location is the lumbar spine, to a greater extent, in the posterior arch. According to published studies, this condition behaves aggressively, due to the root compression generated by its expansion. While there is literature on the surgical treatment of the tumor and its en bloc resection and embolization, there is no experience on the treatment with monoclonal antibodies. There are very few published articles that corroborate a treatment for recurrences or for inoperable or intralesional aneurysmal bone cysts, which leave the possibility open to other techniques. We present the case of a 38-year-old woman with lumbar pain radiating to the thigh. In studies, a tumor was detected, and the needle biopsy and imaging confirmed that it was an aneurysmal bone cyst. We planned the treatment with preoperative embolization and intracompartmental excision by subsequent surgery with the release of the dural sac. At six months, tumor recurrence was observed. Treatment with denosumab was indicated for two years, periodic controls were carried out and the remission of symptoms and improvement in the images were verified.

Keywords : Aneureysmal bone cyst; treatment; relapse; coadjuvant; denosumab.
