A Rare Case of Twisted Large Luteal Cyst in the First Trimester of Pregnancy

Ovarian torsion is a rare but serious complication during early pregnancy, often associated with corpus luteum or functional cysts. We report the case of a 23‑year‑old woman, gravida 4 abortion 3 (G4A3), presenting with acute abdominal pain at 6 weeks and 2 days of gestation. Imaging revealed a large right luteal cyst measuring 88 × 84 × 51 mm with absent Doppler flow, suggestive of torsion. Prompt laparotomy with detorsion and cystectomy, followed by postoperative progesterone support, resulted in successful preservation of the ovary and continuation of the pregnancy. Early diagnosis and timely intervention ensured a favourable maternal and fetal outcome.
