Pyometra is a very uncommon condition in postmenopausal women that rarely improves with standard antibiotic treatments. It is usually overlooked as the patient presents with vague symptoms. Our case presented a postmenopausal woman with sepsis due to a huge pyometra. Swabs for sensitivity, tubercular gene testing, and basic blood workup were done, and the patient was started on intravenous antibiotic therapy. Pyometra drainage could not be done due to thin, friable uterine walls. When the patient had improved, a clinically total abdominal hysterectomy was done after ruling out malignant causes. Delay in the diagnosis of this condition may lead to perforation, which may, in turn, cause peritonitis, which may gravely affect the patient.
