[A woman with a tumour in her lesser pelvis].

A 63-year-old postmenopausal woman was referred for a mass on MRI: a well-defined 13 cm hyperechoic mass with high fat content. Exploratory laparotomy revealed normal ovaries and an enlarged uterus; hysterectomy was performed. Histological examination found uterine lipoleiomyoma, a rare benign type of uterine myoma.
