Purpose : To evaluate radiographic changes and clinical effects after the injection of
steroid injection into simple bone cyst
Materials and Methods : We analyzed plain radiographic and CT findings after the
injection of steriod (methylprednisolone acetate, MPA) into simple bone cyst. Twelve
patients were treated from one to seven times with an intracystic injection of MPA,
80-200mgs per injection. All patients were evaluated by plain film, and four by CT, and
the mean follow-up period was 20 months.
Results : Postinjection plain radiographic findings were as follows : increased internal
radiodensity (n=10), smaller cyst (n=8), cortical thickening (n=7), and radiodensity of
double ring pattern (n=4). CT findings were as follows : increased internal attenuation
(n=4), smaller cyst (n=4) and radiodensity of double ring pattern along the cyst wall
(n=4). All patients improved clinically and radiologically, especially those with
radiodensity of double ring pattern.
Conclusion : The injection of steroid into simple bone cyst is an effective treatment. A
new radiographic finding after injection is radiodensity of double ring pattern along the
cyst wall, and we believe that this indicates progression of the healing process.
