POLYOSTOTIC FIBROUS DYSPLASIA IN A DOG

A young Dobermann Pincher dog with severe right hind leg lameness was admitted to our clinic. A complete radiographic examination showed the presence of cystic lesions in the right tibia and femur and polyostot ic fibrous dysplasia was diagnosed. The distal tibial lesion, associat ed with an incomplete cortical fracture, was treated by surgical curet tage and drainage of the cyst cavity. The other cystic lesions were tr eated conservatively. Radiological, morphological and histological exa minations were then performed to evaluate the recovery phase. At six m onths, the surgically treated tibial lesion showed good ossification o f the fibrous tissue. At twelve months, the examination showed complet e healing of the tibial lesion but the femur lesions still had a cysti c appearance. It appeared that surgical curettage of the cystic cavity alone enables recovery to be achieved in a relatively short period of time.
