Hemophilic pseudotumor is one of the most serious complications of hemophilia 
and is usually treated with extensive surgery. A new treatment approach is 
radiotherapy. Patients with long-bone pseudotumors are usually treated with high 
doses of radiotherapy greater than 1500 cGy. We treated a 13-year-old hemophilic 
boy who had a pseudotumor of the tibia with low-dose radiotherapy (600 cGy). 
There was no complication during the two-and-a-half-year follow-up. Improvement 
of both the clinical and radiological status of the patient was noteworthy. We 
would like to suggest the use of low-dose radiotherapy in patients with 
hemophilic pseudotumors.
