A unicornuate uterus with a rudimentary horn is a rare Müllerian anomaly. The great majority of the rudimentary horns are of non-communicating type (72–85%) [1]. The incidence is estimated at 1 per 100,000 to 140,000 pregnancies [2]. It has poor outcome, and rupture usually occurs in the second trimester leading to maternal morbidity and/or fetal mortality [3]. This is the first case of rudimentary horn pregnancy treated with local methotrexate administration (Figs. 1, 2).
