[Differential diagnosis of acute scrotum by nuclear medicine study].

Sixty-four patients with acute scrotal pain were examined by radionuclide scrotal scanning. We compared clinical, surgical and radionuclide findings. The scrotal scanning is a rapid, non invasive and painless examination with high accuracy in inflammatory disease. But two falsely negative scans in acute testicular torsion warn against this simple method. Torsion of the appendix testis were not recognized by scanning.
