They are the most common form of "testicular" enlargement and present with painless enlargement of the scrotum. On all modalities, hydroceles appear as simple fluid, unless complicated by infection or hemorrhage. [radiopaedia.org]

Risk factors Most hydroceles are present at birth. At least 5 percent of newborn boys have a hydrocele. Babies who are born prematurely have a higher risk of having a hydrocele. [mayoclinic.org]

• Weakness

  For example, a hydrocele might be associated with a weak point in the abdominal wall that allows a loop of intestine to extend into the scrotum (inguinal hernia). A baby's hydrocele typically disappears on its own. [mayoclinic.org]

• Swelling of the Scrotum

  Overview A hydrocele (HI-droe-seel) is a type of swelling in the scrotum that occurs when fluid collects in the thin sheath surrounding a testicle. Hydrocele is common in newborns and usually disappears without treatment by age 1. [mayoclinic.org]

Treatment and prognosis In infants, most hydroceles (around 90%) resolve spontaneously, and they are thought to result from incomplete obliteration of the processus vaginalis 4. [radiopaedia.org]

A hydrocele usually isn't painful or harmful and might not need any treatment. But if you have scrotal swelling, see your doctor to rule out other causes. [mayoclinic.org]

Etiology Congenital There are two main subtypes of congenital hydrocele: communicating hydrocele spermatic cord hydrocele 1,2 In the communicating type, fluid collects around a patent processus vaginalis which failed to successfully obliterate. [radiopaedia.org]
