A primary vaginal stone in a disabled child

BACKGROUND: Primary vaginal stones in children are extremely rare but impor tant because they are often mistaken for bladder calculi on plain film. CASE: A 13-year-old girl was admitted to the hospital with abdominal pain. Physical and serial radiologic examinations found a hard mass anterior to t he rectum. By vaginoscopy, the stone was found at the posterior fornix of t he vagina. CONCLUSION: Primary vaginal stones should be suspected, especially in disab led children. (Obstet Gynecol 2001;98: 978-9.
