Magnetic resonance imaging identified a 7 × 6 cm cystic formation with reduced blood flow and tension in the right adnexa of a 29-year-old patient at 355 weeks gestation (Figure 1a; O: adnexal torsion). The abdomen was entered just beneath the sternum via open laparoscopy because of the advanced pregnancy. Cystectomy was performed after the ovary was detorsioned (Figure 1 b, c, and d; Black arrows: twisted adnexal mass)
Adnexal torsion is very rare in pregnancy, and its incidence is reported at 1–5 in 10 000 pregnancies.

Laparoscopic surgery is associated with a reduced risk of postoperative adverse events.2
Laparoscopic surgery involves less manipulation of the uterus, which causes fewer uterine contractions, and consequently, fewer spontaneous abortions, preterm labours, and premature deliveries.3
Surgeons should be aware that the laparoscopic approach can be safely performed late in pregnancy and may reduce obstetric complications.Consent: Consent to publish these images was obtained from the patient.

- PreviewUne imagerie par résonance magnétique a révélé la présence d'une formation kystique de 7 × 6 cm accompagnée d'une réduction du débit sanguin et de tension dans l'annexe droite chez une patiente de 29 ans à 35 SA + 5 j (figure 1a; O : torsion annexielle). Une laparoscopie ouverte a été effectuée immédiatement sous le sternum pour accéder à l'abdomen en raison de la grossesse avancée. La kystectomie a été réalisée après la détorsion de l'ovaire (figure 1b, 1c et 1d; flèches noires : masse annexielle tordue).
