A woman in her 60s presented with a rare complication of an ovarian cyst which many clinicians may not consider at first presentation. She was admitted with life-threatening staphylococcus aureus sepsis. She presented shocked with a collapse following a 2-day history of diarrhoea, vomiting and pain in the right iliac fossa. She was taken to theatre where a ruptured, widely infarcted left ovarian serous cystadenofibroma was discovered with over 2 litres of purulent fluid exuding from the cyst into the abdomen. She had a left cyst removal, hysterectomy and bilateral salpingo-oophorectomy performed. Histological analysis and molecular gene testing of an incidentally discovered uterine neoplasm revealed an undifferentiated uterine sarcoma. She successfully recovered as an inpatient and was discharged under the care of an oncology team for ongoing management.
