We present two cases of osteoid osteoma in adolescent boys. The lesions were located in the proximal metaphysis of the right tibia and left femoral diaphysis respectively. Doppler duplex color study demonstrated clearly the highly vascular nidus and its feeding artery in one case and only the feeding artery in the second. We believe these are the first descriptions of osteoid osteomas assessed with Doppler duplex color, which was also used as guidance for the percutaneous localization and biopsy.
