What happened, in summary

A 55-year-old woman presented with fatigue, abdominal swelling, constipation, reduced urine output, and a vaginal bulge. Imaging showed a large mass arising from both ovaries with extensive abdominal fluid and findings concerning for advanced spread. She was diagnosed with Stage IV ovarian cancer and started paclitaxel and carboplatin chemotherapy.

During her second treatment cycle, she suddenly experienced a painless gush of fluid from the vagina. Examination found a 3 cm opening in the back wall of the vagina, creating an abnormal connection with the abdominal cavity. Because of the risk of infection, her team decided to operate rather than continue chemotherapy immediately.

She underwent tumor-removal surgery that included removal of the uterus, both ovaries and fallopian tubes, and the omentum, along with repair of the vaginal defect. Final pathology confirmed mucinous adenocarcinoma involving both ovaries with tumor deposits in the omentum.

Three weeks after surgery, she restarted chemotherapy and completed 4 additional cycles. Over 8 months of follow-up she remained clinically well, her CA-125 had fallen substantially, and imaging showed no visible tumor.
