case_images: The X-ray (A) and the MRI (B) demonstrated that the tumor involved the first metacarpal. The SPECT (C) showed no distal metastasis.

case_images: The grip strength was 5 kg (30 kg on the contralateral side), and the key-pinch strength was 1 kg (8 kg on the contralateral side). The anteroposterior and lateral radiograph displayed an osteolytic bone destruction in the first metacarpal (Figure 1A). Magnetic resonance imaging (MRI) showed intramedullary lesion of high signal intensity with clear boundary (Figure 1B). Pulmonary computed tomography (CT) scan and single-photon emission computed tomography (SPECT) scan indicated no distal metastasis and only the left first metacarpal bone was involved (Figure 1C).
