[Pregnancy in a rudimentary horn of the uterus].
The cases of pregnancy in the rudimentary horn are probably the rarest Mullerian anomalies. More often the pregnancy ends with an abortion in the first or the end of the second trimester. Extremely rarely (1% of the cases) end with a live birth. The authors examine and describe a case which successfully ended with a birth of a live fetus in 32 gestation week after a rupture of cornual pregnancy. Special attention is paid to the diagnostical difficulties, which are characteristic for these cases. It is reasonable in the cases of extrauterine pregnancy to think of a pregnancy in the rudimentary horn as well.
