Evaluación clínica-radiográfica de la efectividad de las infiltraciones percutáneas de acetato de metilprednisolona en el tratamiento de los quistes óseos esenciales.

Objective: To evaluate the effectiveness of percutaneous injections of methylprednisolone acetate in the treatment of essential bone cysts and to identify possible predictors of therapeutic response and recurrence. Material and Methods: Retrospective study of 32 patients (23 male, 9 female) 7 years mean age, with diagnosis of essential bone cyst. Percutaneous injections of methylprednisolone acetate were used in 21 cases as sole therapy and were followed clinically and radiographically to determine the response. Results: There was complete healing in 7 of the 21 patients treated with methylprednisolone acetate injections, partial resolution in 10 patients, persistence of the cyst in 2 patients and recurrence in other 2 patients. Conclusions: Therapeutic response of essential bone cysts to infiltration of methylprednisolone acetate is unpredictable, requiring multiple injections spaced over time to achieve cyst obliteration, usually incomplete.
