| Abstract: | We report the case of a 43-year-old man who presented with an osteolytic and expansive lesion in the left distal femur mimicking
a giant cell tumor. Magnetic resonance imaging (MRI) showed that most of the lesion was cystic, and histological examination
revealed fibrous dysplasia with marked cystic degeneration. Radiographic findings of cystic fibrous dysplasia in the end of
a long bone may be similar to those of a giant cell tumor, and a biopsy is essential for the final diagnosis.
