High-energy, low-dose radiation therapy for aneurysmal bone cyst. Report of a case.

Whereas curettage and bone grafting of aneurysmal bone cysts (ABC) are generally accepted, recurrence is not uncommon and surgery is hazardous when the lesion is large and adjacent to the growth plate. High-energy, low-dose radiation in an eight-year-old girl with this lesion of the distal tibia was successful with no recurrence at the three-year follow-up examination. No complications have ensued, and excellent function has been sustained. Further evaluation of this form of radiation treatment is important in similar situations in which surgical excision of ABC may carry high risks.
