Acute pelvic organ prolapse in an 11-month-old infant.

There exist several reports of pelvic organ prolapse in high-risk neonates, but acute pelvic organ prolapse in a healthy infant has never been reported. In the current case, the parents first noted their 11-month-old infant with a mass protruding from the vagina after playing in a baby walker. Third-degree uterine prolapse was subsequently diagnosed after careful physical examination and pelvic ultrasonography. Under general anesthesia, the uterus was replaced after emptying the bladder. No sequelae were noted during 6 months of follow-up.
