case_images: Initial radiographic films (Figure 1) were read as unremarkable; however, given high clinical suspicion of osteoid osteoma, an MRI was obtained which demonstrated a circular hypointense lesion along the dorsal aspect of the trapezium (Figure 2) suspicious for an osteoid osteoma.

case_images: CT was ordered to further characterize the lesion. CT imaging demonstrated the same defect yet slightly larger (Figure 3).
case_images: Photomicrograph of the osteoid osteoma. The tumor is composed of haphazardly interconnected trabeculae of osteoid and woven bone (hematoxylin and eosin; original magnification, x5).
