Twelve children (9 boys and 3 girls, ages 1 1/2 -12 yrs.) with unicameral bone cysts were treated with triamcinolone acetonide (4 patients) or methylprednisolone acetate (8 patients) injected directly into the cyst cavity. Postinjection radiographic changes that indicate healing were noted in eight patients and included: reduced size of the cyst cavity, increased internal density, cortical thickening, and remodeling in the vicinity of the cyst. Additional injections were required in three patients because of delayed or partial healing. Recurrence of the cyst (1 case) was signaled by renewed rarefaction and bone expansion.
