A false-positive scan for testicular torsion and false-negative scan for epididymitis

Abstract

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.
