title: Sonographic appearance of a giant cell tumor of the humerus.
abstract: The sonographic presentation of intramedullary bone tumors is rarely reported. A patient with right shoulder pain for 7 months was clinically diagnosed with shoulder impingement syndrome. Sonographic examination revealed a segment of thinning cortex with a large, heteroechoic tumor deep in the greater tuberosity of the humerus. Increased peripheral vascularity of the tumor was observed in the power Doppler mode. The definite diagnosis was a giant cell tumor, whose sonographic findings are discussed.
