Introduction:

The giant cell tumor continues to be one of the bone tumors with many controversies in diagnosis and management, by orthopedists, radiologists and pathologists.

Objective:

To enrich the diagnosis of this disease from the contribution of imaging techniques.

Casereport:

We report the case of a 33-year-old male patient, referred to the Orthopedics consultation for presenting an increase in volume in his knee, with months of evolution, which progressively worsened until functional impotence. Physical examination showed a marked increase in volume, so imaging studies are indicated.

Conclusions:

Early diagnosis helps to improve the lifestyle of these patients. Surgical treatment is the most indicated in giant cell tumors, since it achieves good results both in the treatment of the primary tumor and recurrences.
