AbstractA prospective study of 1494 new referrals for scrotal ultrasound was performed over a 5 year period. In 610 patients referred with a clear clinical diagnosis of epididymal disease, and no clinical suspicion of malignancy, ultrasound diagnosed unsuspected testicular tumours (seven malignant, one benign) in eight patients. In this series one case was counted as false negative for ultrasound diagnosis of tumour, as tumour was the differential diagnosis and not the primary diagnosis. No other patients diagnosed as having benign disease by ultrasound have subsequently been shown to have malignant disease. Sensitivity and specificity of ultrasound for the diagnosis of testicular malignancy in this series is 98% and 99.8% respectively. It is concluded that all patients with scrotal symptoms should be examined by ultrasound in order to achieve the maximal clinical benefit from the early diagnosis of testicular tumours. The implications of this are discussed.
