A possible cause of misinterpretation on radionuclide imaging: Chilaiditi's syndrome.

The authors of this work present two patients, diagnosed with lymphoma and prostate cancer, referred to nuclear medicine department for a gallium-67 scan and a bone scan, respectively. The abnormal accumulation of the radioactivity gave rise suspicion for possible other pathologies. Successive computed tomographic imaging revealed that the patients had had Chilaiditi's syndrome. The authors present these cases to draw attention for the possibility of misinterpretation of the scans due to distribution of radioactivity in this syndrome.
