Background: Corpus luteum cysts are common in early pregnancy and usually regress spontaneously by 12 
weeks of gestation. However, torsion of a corpus luteum cyst during pregnancy is rare and poses a significant 
threat to maternal and fetal well-being if not promptly recognized and managed. 
Case Presentation: A 29-year-old primi-gravida at 12 weeks of gestation presented with acute abdominal pain 
following a single episode of vomiting and severe right iliac fossa and groin pain. On examination, she was 
hemodynamically stable with localized tenderness in the right iliac fossa. Ultrasonography revealed a single live 
intrauterine pregnancy (11 weeks 5 days) with a right ovarian cyst (5 × 4 × 4 cm). Conservative management 
provided transient relief, but pain recurred with bradycardia and worsening tenderness. Despite a differential 
diagnosis of appendicitis, clinical suspicion of ovarian torsion was high. Emergency laparotomy revealed a twisted 
right ovarian cyst (7 × 6 × 4.5 cm), for which right oophorectomy was performed. 
Outcome: Histopathology confirmed a corpus luteum cyst. Postoperative recovery was uneventful. Careful 
antenatal monitoring and follow-up were continued throughout pregnancy. The patient later delivered a healthy 
female infant weighing 2.8 kg via lower-segment caesarean section on 25 December 2024. Both intraoperative 
and postoperative periods were uneventful. 
Conclusion: Twisted corpus luteum cyst in early pregnancy is a rare but critical emergency. Early diagnosis, 
prompt surgical management, and vigilant antenatal follow-up are essential for favourable maternal and fetal 
outcomes.
