Rudimentary horn pregnancy associated with pre-eclampsia

Abstract

The unusual association of pre-eclampsia with a pregnancy in the rudimentary horn of the uterus in a multigravid patient is reported. The infrequent development of rudimentary horn pregnancy beyond the twentieth week of gestation may explain the rarity of this complication. The possible effect of rapid distension of the rudimentary horn with exposure of the myometrial surface to overwhelming fetal antigenic proteins may be of relevance in the development of pre-eclampsia in this case.
