title: Aneurysmal bone cyst of the spine.
abstract: The cases of twenty-two patients with an aneurysmal bone cyst of the spine above the sacrum were analyzed with regard to sex, age, site, symptoms, and radiographic findings. Four patients had extension of the lesion to the adjacent vertebra or rib, and twelve patients had neurological deficits. The primary treatment was either radiotherapy or surgery alone, or surgery and radiotherapy combined. No recurrences were found in patients who were treated with surgery alone or with surgery and radiotherapy, while three of the six patients who were treated with radiotherapy had a local recurrence, two of which were fatal. The patients with neurological deficits recovered after healing of the cyst.
