Abstract
Sonographic findings in 26 patients with diffuse testicular disease were retrospectively analyzed for features to differentiate diffuse neoplasms from diffuse orchitis or infarct. Diffuse neoplasms were associated with moderate to marked enlargement, globular shape, lobulated contour, and heterogeneous texture of the testis; the epididymis and scrotal skin were normal. In diffuse inflammatory disease, the testis was mild to moderately enlarged, the oval shape and smooth contour were preserved, and the texture was generally homogeneous; the epididymis was often enlarged, and scrotal skin was almost always thickened.
