title: Immersion ultrasound of testicular pathology.
abstract: A water-coupled free-immersion ultrasound scanner, the Octoson, was used to study 70 patients with scrotal masses. Scrotal swelling can be identified accurately as intrascrotal fluid collections of solid lesions, and an intra- or extra-testicular origin can be determined precisely. In most cases, testicular tumors can be distinguished from inflammatory conditions. Immersion testicular ultrasound can disclose the site, delineate the extent, and characterize the nature of intra- and extra-testicular lesions.
