title: Rupture of pregnant noncommunicating rudimentary uterine horn with fetal salvage: a case report.
abstract: A rare case of noncommunicating rudimentary uterine horn pregnancy is described. The pregnancy proceeded to twenty-six gestational weeks when the rudimentary uterine horn ruptured as the patient had signs and symptoms of massive hemoperitoneum. An emergency exploratory laparotomy revealed incomplete rupture of the gravid rudimentary horn. A viable female infant with a birth weight of 633 g was delivered. The rudimentary horn had no direct communication to the uterine cavity of the unicornate right uterus. Immunohistochemical examination showed that the excised uterine horn was filled with placental tissue without an intervening layer of decidua basalis.
