title: Spermatic cord torsion: diagnostic limitations.
abstract: To distinguish spermatic cord torsion from other intrascrotal pathology, scrotal ultrasound and radionuclide scanning have been highly recommended on the basis of both clinical and experimental studies. We review the data from six patients in whom ultrasound or nuclear medicine examination was misleading. We emphasize that history, physical examination, and urinalysis remain the cornerstones of the diagnosis of spermatic cord torsion. Scrotal ultrasound and nuclear medicine scans are useful adjuncts and are reassuring when in agreement with the clinical picture. However, they are not 100% sensitive or specific, and a negative study should not prevent emergency operative exploration of a clinically suspicious lesion.
