Huge ovarian endometrioma—a case report
This report details a rare case of a 26 cm, 5 kg ovarian endometrioma in a 33-year-old woman, diagnosed definitively by postoperative pathology despite preoperative findings suggestive of malignancy.

This paper is a case report of a 33-year-old woman with a very large abdominopelvic septated cystic mass (24.3 × 17.6 × 16.6 cm; ~5 kg; 26 × 18 × 17 cm) that extended to the xiphoid, evaluated with ultrasonography showing no neovascularization and mild CA125 elevation but a more prominent CA19-9 increase. Despite differential diagnosis concerns because the mass resembled ovarian cancer (multiple thick internal septations and high CA19-9), she underwent right salpingo-oophorectomy; frozen section and final pathology confirmed a benign endometrioma containing 3,250 ml of chocolate-brown fluid and hemorrhagic necrotic endometrial tissue. A key limitation is that, as a single case, it cannot establish diagnostic accuracy or generalizable markers, and preoperative imaging did not yield a definitive diagnosis. This paper is centrally about endometriosis — specifically a rare report of a huge ovarian endometrioma misdiagnosed preoperatively.
