title: [A woman with a special cervix].
abstract: A 40-year-old woman (nulligravida) presented with abnormal cervical cytology. At colposcopy a double external uterine os was discovered with a levonorgestrel intra uterine contraceptive device placed in the opening on the left side. Ultrasound revealed an uterus bicornis bicollis. Despite frequent examinations, the abnormality had not been discovered earlier. Therefore, contraception and cervical cytology sampling had most likely been inadequate.
