title: Successful treatment of aneurysmal bone cyst of the proximal fibula with embolization.
abstract: We present an 8-year-old girl with evolution of an aneurysmal bone cyst of the proximal fibula after intralesional surgery, treated successfully with one selective transfemoral embolization with N-2-butyl-cyanoacrylate. By the first 5 days, the patient experienced complete pain relief. Post-embolization imaging follow-up showed progressive homogenous trabecular bone formation and gradual reduction of the size of the lesion. These findings canceled our initial consideration for surgical treatment. Three years after the embolization, healing of the lesion and remodeling of the proximal fibula were observed without evidence of recurrence. Our successful results with excellent response seen 3 years after embolization are in favor and should increase the awareness of surgeons regarding embolization for aneurysmal bone cysts in difficult anatomic locations such as the proximal fibula.
