title: Use of radioisotope scan in evaluation of intrascrotal lesions.
abstract: There were 98 patients with a variety of intrascrotal lesions studied with a radioisotope 99mtechnetium-pertechnetate scanning technique. Retrospective analysis in 50 patients subjected to an operation revealed a 94 per cent accuracy of the scan in the differential diagnosis of testicular torsion and epididymitis as compared to a clinical accuracy of 48 per cent. In 7 patients with a scan diagnosis of epididymo-orchitis with abscess the diagnosis was confirmed during the operation or by followup examination. While the scan has been a simple, safe, rapid and reliable technique to differentiate acute and subacute lesions, it has proved to be of limited diagnostic significance in cases of chronic intrascrotal lesions and carcinoma.
