technetium-tc-99m-exametazime and Foreign-Bodies

The case of an 11-year-old boy with recurrent abdominal pain is presented. Physiological findings were found normal during a clinical investigation, as well as many laboratory tests, ultrasonography and CT of abdomen. Only a high level of sedimentation rate and the focus of increased activity in the sacral region on scintigraphy using 99mTc-HMPAO (hexamethypropyleneaminooxime) labelled leukocytes were found. The other findings on bone scintigraphy, X-ray and MRI led to a deflection of the correct diagnosis. The real culprit proved to be an ingested foreign body (a piece of a wooden skewer) that the patient failed to reveal.

Radionuclide brain scintigraphy is a commonly performed examination for the confirmation of brain death. Although the absence of scintigraphically detectable flow of lipophilic tracers to the brain combined with the lack of uptake in the brain is considered consistent with brain death in the appropriate clinical scenario, the cause of death itself is usually not apparent on the scan. A case of bullet track and bullet visualization during a radionuclide brain death study with Tc-99m hexamethylpropyleneamine oxime (HMPAO) is described.
