title: [Giant cell tumor of the tendon sheath: characteristic findings of the bone scintigraphy and correlation with MRI].
abstract: We report 3 cases of an unusual tumor, that is, the giant cell tumor of the tendon sheath. The patients consulted due to the appearance of a well-defined, painless, soft tissue mass with mild-to-moderate inflammation located in the thumbs or toes. These clinical data, together with the bone scan findings, oriented the diagnostic suspicion that was confirmed by a pathology study of the tumor after resection. This work has aimed to review the characteristics of the bone scan (BS) image of this tumor and its correlation with the conventional X-ray imaging and magnetic resonance imaging (MRI).
