A case of Rokitansky syndrome is described where the typical anomalies of the entity were associated with cribriform hymen. The appearance of the external genitalia led to an erroneous diagnosis of complete vaginal agenesis and to surgical creation of an artificial vagina by the McIndoe technique at the patient's age of 19. She had a satisfactory sexual life subsequently. Ten years following the surgery, routine examination revealed that the patient had an essentially normal vagina with a blind upper ending. Prior to this, she and her husband had been unaware of the fact that their marital relations were conducted through her natural vagina during the years of their sexual activities.
