Primi at 16 weeks and 5 days of Gestation with Hypovolemic Shock Secondary to Ruptured Rudimentary Horn Ectopic Pregnancy: A Case Report.

Abstract

Abstract: Developmental anomalies of genital tract result from defective fusion and absorption of various parts of Mullerian ducts in fetal life. Rudimentary horn pregnancy (RHP) is a rare occurrence of one in 76,000 and one in 160,000. We present a case of a 24-year-old primigravida with ruptured RHP initially managed in the line of an intrauterine pregnancy with severe anemia. Hemodynamic instability made us suspect ruptured RHP and lifesaving laparotomy was performed for the same. A 1.5-liter hemoperitoneum was encountered with a right RHP. 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.
