Hydrocele is usually associated with patent processus vaginalis. Painless swelling is usually present. Scrotal contents can be visualized with transillumination. Incarcerated hernia may be diagnosed by careful examination of the inguinal canal.

Testis tumor produces scrotal enlargement, only rarely accompanied by pain. The presentation is rarely acute.

In idiopathic scrotal edema, the scrotal skin is thickened, edematous, and often inflamed. The testis is not tender and is of normal size and position.
