The unusual cause of recurrent abdominal pain in an 11-year-old boy

Abstract

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.
