Primigravida with Hypovolemic Shock Secondary to Ruptured Rudimentary Horn Ectopic Pregnancy: A Case Report

Developmental anomalies of genital tract result from defective fusion and absorption of various parts of Mullerian ducts in fetal life. Rudimentary horn pregnancy is a rare occurrence of one in 76,000150,000. We present a case of a 24-year-old primigravida with ruptured rudimentary horn pregnancy initially managed in the line of an intrauterine pregnancy with severe anemia. Hemodynamic instability made us suspect ruptured rudimentary horn pregnancy and lifesaving laparotomy was performed for the same. A 1.5 liter hemoperitoneum was encountered with a right rudimentary horn pregnancy. Multiple adhesions were present with necrotic tissue adherent and clumped together as tubo-ovarian mass. Resection of rudimentary horn was performed. We report this case to emphasize the need to consider rare uterine anomalies as a possibility in patients presenting with acute abdomen in early pregnancy. So, obstetricians can consider these rare entities in differential diagnosis and management.
