Spontaneously reduced testicular torsion. A pitfall in radionuclide scrotal imaging.

The radionuclide scrotal scan is highly accurate in the differential diagnosis of acute torsion vs epididymo-orchitis. While the scan findings of increased flow through the spermatic cord and increased static scan activity suggest inflammation, its appearance is not always diagnostic of inflammatory disorder. That this may also occur after reduction of torsion has not been emphasized in the literature. A case report of spontaneous reduction of testicular torsion is presented which demonstrates both increased flow and increased static image activity mimicking epididymitis.
