By L Albuquerque, J Pimentel, L Távora, J L Antunes, A G Ferreira and J Campos

Abstract

Aneurysmal bone cysts (ABC) are rare bone tumors of controversial pathogenesis. In 15% of cases, they are localized in the vertebrae. Despite the absence of anaplasia, their volume and localization are often responsible for incomplete surgical resection. The authors present 5 cases of primary vertebral ABC, 4 females and one male, localized in cervical (3 cases), dorsal (1 case) and lumbar (1 case) spine. Symptoms included rachialgia and torticollis. Radiological and histopathological examination disclosed the typical features of ABC. Pre-operative embolization (in 3 cases) and surgery (complete exeresis in all cases except one) were the therapeutic procedures. During a 39 month median period of follow-up, there was one local recurrence. The only case of incomplete exeresis show not did any evidence of progression until 36 months after operation.Aneurysmal bone cysts (ABC) are rare bone tumors of controversial pathogenesis.
