Abstract

The aim of this study was to describe treatment options and develop a follow-up regime for the aneurysmal bone cyst, a neoplastic bone lesion with a noticeable recurrence rate. Reports of 28 patients and a mean follow-up of 42.2 months treated multidisciplinary were analysed. Data were complemented by a literature review including 790 patients. Patient age was from seven to 57 years, in line with the literature (1-69 years). Lesions most frequently affect long bones, spine and pelvis ; pain is the most common symptom. Treatment modalities vary, recurrences occurred in 26.1% in our series, rates ranged from 0-60% in the literature, with the vast majority within 2 years. With regard to the findings we propose, irrespective of treatment, a follow-up regime including clinical survey and imaging, best with MRI, at 3 months, 6 months and at half-yearly intervals within the first two and yearly within the third to fifth year.
