Rare anomalies include scrotal agenesis, hypoplasia, ectopia, or hemangioma; penoscrotal transposition; and bifid scrotum.
A congenital hydrocele is a collection of fluid in the scrotum between layers of the tunica vaginalis. It may be isolated (noncommunicating) or may communicate with the abdominal cavity through a patent processus vaginalis (a potential hernia space). Hydrocele manifests as a painless, enlarged scrotum. The condition may resolve spontaneously but usually requires repair if it persists after 12 mo or if it enlarges.
