ABSTRACT
Enterogastric reflux occurs in normal and abnormal conditions. When pronounced, it is a nonspecific indicator of pathology. There are relatively few published reports discussing enterogastric reflux as a prominent finding on cholescintigraphy. A unique case of pronounced enterogastric reflux from an obstructing duodenal hematoma is presented.

A 17-year-old boy underwent a radionuclide scan for testicular torsion. The scan demonstrated a cold defect with a warm ring, indicating a "missed" testicular torsion. Operative findings, however, demonstrated epididymitis. A false-positive radionuclide study is described in a patient with epididymitis and the literature of scintigraphy in testicular torsion is reviewed.

The authors describe a radionuclide technique for evaluating intrathecal and intraventricular infusions by surgically implanted drug pump delivery systems. Sixteen patients underwent flow studies, performed by injecting 500 mu Ci of indium-111 DTPA into the pumps. Early and delayed images were obtained. These studies enabled distinction among functioning pumps, nonfunctioning pumps, and obstructed or occluded catheters. We conclude that indium-111 DTPA flow studies provide an excellent way to assess these drug pump delivery systems.
