Misleading 67Ga uptake and serial bone scintigraphy in osteoid osteoma

5 consecutive patients with osteoid osteoma were examined with bone scintigraphy and 67Ga scintigraphy. In 2 cases a 'three-phase' bone scintigraphy was performed. Scintigraphic features included obvious 67Ga uptake and diffusely increased accumulation on blood pool images. Thus, osteoid osteoma may possess the same scintigraphic characteristics as osteomyelitis.
