MAGNETIC-RESONANCE-IMAGING IN THE DIAGNOSIS OF LOCALIZED PIGMENTED VILLONODULAR SYNOVITIS OF THE ANKLE - A CASE-REPORT

The use of magnetic resonance imaging (MRI) in pigmented villonodular synovitis (PVS) has been well described in the literature. MRI has bee n used predominantly with diffuse PVS lesions. We recently had a patie nt with an unusual case of localized PVS of the ankle with bone and ca rtilage destruction. Preoperative MRI was useful in the diagnosis of l ocalized PVS and in the planning for surgery. MRI in a patient with th is lesion had not been documented previously, but should be considered whenever PVS, either diffuse or localized PVS, is suspected.
