Pediatric Cervical Aneurysmal Bone Cyst Treated by Endovascular Approach

Aneurysmal bone cyst (ABC) is a rare, benign, and expansible bone lesion, occurring mainly in childhood. Although most lesions are located at the metaphysis of long bones, they can also be found in flat bones and spine.

We report a case of a 16-year-old boy with cervical ABC treated by endovascular embolization. The afferents were occluded as a preoperative preparation for surgery; however, as the patient became asymptomatic after the procedure, the family refused surgery. Image at 1-year follow-up showed reduction and ossification of the lesion.

Endovascular treatment decreases surgical morbidity by reducing blood loss, which is particularly important in the pediatric population. This therapeutic option may also halt ABC growth in selected cases.
