Multiple-view scintigraphy for localization of osteoid osteoma.

A circumscript accumulation of 99mTc-MDP in the spine of a patient, presenting with back pain and negative radiographs, was histologically confirmed to be an osteoid osteoma. As radiological procedures failed to localize the lesion, this was accomplished by means of posterior and lateral view bone scintigrams as well as by single photon emission tomography. The role of scintigraphy in patients suspected of having osteoid osteoma and the possibility of localizing the lesion before and during surgical intervention are underlined.
