Abstract

Radionuclide scrotal scintigraphy with 99m Tc-pertechnetate is an easy, well established, sueful and readilyavailable technique for evaluation of acute scrotum. We studied 41 cases of radionuclide scrotal scintigraphy andthe results were as follows; 1. The over all diagnostic accuracy of scrotal scintigraphy waas 93%(38/41 cases). 2.Scrotal scintigraphy was very useful and accurate in differential diagnosis of epididymo-orchitis and testiculartorsion in patient with acute scrotal pain and swelling, while there was some limitation in differential diagnosisof hematoma from acute epididymo-orchitis or torsion. 3. scintigraphy of epididymoorchitis showed increasedperfusion and radiocativity in the epididymis and/or testis and its diagnostic accuracy was 90%(19/21 cases) 4.Acute testicular torsion showed normal flow in perfusion and cold defect occupying affected testis in staticimage, while missed torsion showed slightly increased flow in perfusion image and cold defect surrounded by anuniform rim of hyperactivity (halo sign). Diagnostic accuracy of testicular torsion was 86%(6/7 cases).
