Aneurysmal bone cyst: a report of three cases.

Three children presenting with aneurysmal bone cysts are described. The first patient was 10 months old with a cyst of the scapula. The second was more typical but his cyst was treated initially as a malignant tumour. In the third child the second cervical vertebra was affected which posed considerable problems of management; it was treated by radiotherapy. Despite the problems all 3 children have made a good recovery.
