Ovarian ectopic pregnancy is rare and constitutes around 3% of all ectopic pregnancies. Its presentation is similar to tubal ectopic pregnancy and is difficult to diagnose based on the presentation and ultrasound findings. Here, we describe one such case which we encountered in our practice. Primigravida patient at early gestation presented with vaginal spotting and pain in lower abdomen. She was suspected as ruptured ectopic pregnancy based on examination and ultrasound findings. Immediate laparotomy was performed and patient was diagnosed to have ruptured ovarian pregnancy intraoperatively. Partial ovariotomy was performed and the case was successfully managed. Histopathology confirmed the diagnosis. Surgery is the mainstay of definitive diagnosis and treatment. Identifying these cases early is imperative as such patients can collapse suddenly and there are high chances of maternal morbidity and mortality.
