Diagnosis of acute testicular torsion using radionuclide scanning. 1983

O M Levy, and M C Gittelman, and A M Strashun, and E L Cohen, and E J Fine

We analyzed retrospectively 99mtechnetium scrotal scan findings in 37 patients with acute scrotal pain. Correlation between scan interpretation, and either surgical findings and/or final clinical diagnosis revealed an accuracy of 89 per cent. Only 1 false negative and 3 false positive results were recorded. Scan data revealed a positive predictive value of 75 per cent, negative predictive value of 96 per cent, sensitivity of 90 per cent and specificity of 89 per cent. An inter-institutional observer study also was conducted to assess reliability of the scan, resulting in an 88 per cent agreement. The testicular scan has been found to be an accurate and reliable method to distinguish between epididymo-orchitis and testicular torsion.

D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D003937 Diagnosis, Differential Determination of which one of two or more diseases or conditions a patient is suffering from by systematically comparing and contrasting results of diagnostic measures. Diagnoses, Differential,Differential Diagnoses,Differential Diagnosis
D004823 Epididymitis Inflammation of the EPIDIDYMIS. Its clinical features include enlarged epididymis, a swollen SCROTUM; PAIN; PYURIA; and FEVER. It is usually related to infections in the URINARY TRACT, which likely spread to the EPIDIDYMIS through either the VAS DEFERENS or the lymphatics of the SPERMATIC CORD. Epididymitides

D013086 Spermatic Cord Torsion The twisting of the SPERMATIC CORD due to an anatomical abnormality that left the TESTIS mobile and dangling in the SCROTUM. The initial effect of testicular torsion is obstruction of venous return. Depending on the duration and degree of cord rotation, testicular symptoms range from EDEMA to interrupted arterial flow and testicular pain. If blood flow to testis is absent for 4 to 6 h, SPERMATOGENESIS may be permanently lost.
