[Ultrasonic studies in gonadal dysgenesis]

Authors studied the internal genital organs of patients with gonadal-dysgenesis by ultrasonography. Streak gonads confirmed by laparotomy and histology have characteristic signs with ultrasonogram as follows: In the middle of the screen, or a little laterally, deeper than the normal uterus used to be, there is a small echo-free territory, which indicates the rudimentary uterus. On both sides in some cases Fallopian tubes were detectable. They give a centrally pointed echo-free pattern with a few mm in diameter, and a tube-like shape. On the place where one usually finds the echo-free outline of the normal ovaries, a zone of multiple echo's is visible. On base of their experiences, authors regard ultrasonic technique as a useful additional diagnostic procedure in cases of gonadal-dysgenesis.
