Distinctive ultrasonographic finding of complete uterine rupture in early mid-trimester.

In many cases of uterine rupture, diagnosis is often impossible when characteristic clinical symptoms are absent. We encountered a case of suspected peritoneal pregnancy in which we were able to make a definitive diagnosis by ultrasonography of complete uterine rupture in early mid-trimester. The possibly distinctive finding is the high-echo area that extends from the endometrium to the uterine serosa. This contiguous, highly echogenic finding should be recognized as characteristic of complete rupture of the uterus.
