title: Huge ovarian endometrioma that grew after menopause: Case report.
abstract: Endometriomas occur in women of reproductive age and are rare after menopause. A 56-year-old gravida 3 para 2 woman complained of abdominal fullness that had gradually worsened over approximately one year (i.e. 5 years postmenopause). Diagnostic imaging revealed a cystic lesion that extended to just below the diaphragm. An ovarian cystoma of low malignancy was suspected. The preoperative blood test indicated normal estradiol levels at 12.6 pg/mL. She underwent bilateral adnexectomy and total hysterectomy. The appendages on the affected (i.e. right) side weighed approximately 12 kg. An ovarian endometrioma with benign pathology was diagnosed. Postmenopausal endometrioma can occur even in patients with normal postmenopausal estradiol values who are not receiving exogenous hormones. These patients require careful follow-up.
