Giant cell tumor of the fourth metacarpal bone

Giant cell tumor is among the rare tumors of the bone. We present a case of metacarpal giant cell tumor with radiographic, computed tomographic (CT) and histologic findings, as well as grey scale and Doppler sonographic features. We also present the “doughnut”-shaped appearance on scintigraphy of the lesion, which has not been shown on a metacarpal giant cell tumor.
