Unilateral pulmonary metastases from Ewing's sarcoma shown in a technetium-99m-methylene-diphosphonate bone scan.

A 32-year-old man with a history of painful swelling of the right ankle underwent bone scintigraphy, which showed increased uptake in the right ankle and also unexpected diffuse uptake throughout the right hemithorax. A single photon emission tomography scan performed after the intravenous injection of 740 MBq of technetium-99m methylene-diphosphonate ((99m)Tc-MDP) showed abnormal uptake throughout the right lung. Computed tomography (CT) revealed a large mass in the right lower lobe.

The prevalence and significance of increased gastric wall radiotracer uptake in sestamibi myocardial perfusion SPECT.

Background: Limited available data indicate that a specific pattern of increased gastric wall radiotracer uptake is associated with dyspepsia. Our purpose was to evaluate the frequency of this finding and its relation with dyspeptic evidences.

Method: 1056 consecutive outpatients referred for myocardial perfusion SPECT were interviewed concerning the dyspeptic symptoms, current gastric medications and previous gastroduodenal interventions.
