Scintigraphy for the diagnosis of testicular torsion and differential diagnosis of acute intrascrotal processes.

Twenty-five patients suffering from acute painful testicular processes were subjected to scintigraphy. Testicular torsion in the early and delayed phases were diagnosed with 100% accuracy, but one out of 7 cases of epididymitis was wrongly recognized as negative. Interoperative diagnosis in two cases of hydatid torsion proved the foregoing scintigraphic finding to have been wrong. Nevertheless, scintigraphy was found to be reliable in testicular torsion diagnosis.
