Radiological findings in three cases of persistent müllerian duct syndrome.

We report three cases of persistent Müllerian duct syndrome, which is a rare form of inherited male pseudohermaphroditism characterized by the presence of a uterus and tubes in otherwise normally virilized 46,XY males. We emphasize the usefulness of ultrasonographic study of the pelvis and inguinal areas in the preoperative diagnosis, which is difficult. We recommend that ultrasound be performed routinely in bilaterally cryptorchid patients.
