Abstract

Methods

The images of bone scan and clinical charts of total 91 patients with confirmed TIO were retrospectively reviewed. The image findings were compared with the results of other imaging studies, surgical notes, histopathologic examinations and clinical follow-ups.

Results

In 76.9% (70 of 91) of the patients, the findings of bone scintigraphy did not correspond to the sites of the causative tumors, which were subsequently located. However, in 23.1% of the patients (21 of 91), the sites of the causative tumors corresponded to one of the abnormal technetium 99m-methyl diphosphonate activity on bone scintigraphy. More importantly, 6 tumors corresponded to the dominant activity on bone scintigraphy.

Conclusions

Although findings of whole-body scintigraphy are nonspecific in patients with TIO, careful evaluation of bone scintigraphy results can be helpful in guiding further evaluation in some patients.
