Background: Hydrometrocolpos due to vaginal atresia is a rare congenital anomaly characterized by an abdominal mass; girls with this anomaly are prone to develop obstructive uropathy due to compression of bladder and/or urethra.
Case: We report the case of a two-month-old girl who presented with an abdominal mass and dysuria. She was found to have a lower vaginal atresia and hydrometrocolpos by MRI. She was successfully treated surgically by reconstruction of vagina and drainage of 100 ml serosanguinous fluid. Summary and Conclusion: Early diagnosis and surgery reduces the incidence of complications such as infection, rupture and renal failure. Diagnosis may be suspected prenatally by ultrasonography and confirmed postnatally by magnetic resonance imaging.View pdf
