title: [Echographic differential diagnosis of scrotal contents. A contribution to evaluation of the method].
abstract: Ten patients were selected from a clinical material comprising 336 sonograms of the scrotal contents in order to discuss the differential diagnosis of testicular and extra-testicular conditions. The decision whether a tumour is testicular or extra-testicular does not usually pose a problem, but may be impossible for small peripheral tumours. The shape of the epididymis and vas deferens and the structure of the testes is of significance in the differentiation between torsion and epididymitis. Rare diseases--myxoliposarcoma, infiltrating urothelial carcinomas from the bladder growing along the vas, lymphangiomas--are considered in the differential diagnosis of space-occupying lesions. Lymphangiomas produce a typical appearance on ultrasound. The criteria for the diagnosis testicular trauma, rupture, parenchymal tears and haematocoeles are defined. Differentiating liquid from solid is rarely a problem. A testicular abscess in the presence of chronic orchitis can simulate a solid tumour.
