Introduction Uterine lipoleimyoma (UL) is a rare benign tumor affecting especially perimenopausal and menopausal women and it is often diagnosed as a malignant tumor in radiology findings.

Methods We report a case of a female patient aged 66 years treated for left parauterine mass in Salah Azaiz Institute of Oncology, Tunis, Tunisia in March 2020.

Case Report A 66-year-old woman with medical history of diabetes, high blood pressure and coronary artery disease consulted for a pelvic mass fortuitously discovered on a CT scan. The physical exam was normal. The thoracic-abdominal pelvic scan showed a multi-partitioned well-defined left ovarian mass of fat density, measured 113 mm in its great diameter. Tumor markers CA 125, CA 19–9 and ACE were negative. The diagnosis of ovarian teratoma was suspected on radiological findings. We decided to perform an exploratory laparotomy, instead of laparoscopy due to COVID 19 outbreak. Intraoperatively, we found a uterine mass with fibroid appearance. The patient underwent total non-conservative hysterectomy. The frozen section concluded to the diagnosis of UL.

The postoperative course was straightforward. The diagnosis of UL was confirmed by the final histologic examination.

Conclusion The resemblance between UL and ovarian teratoma on the CT scan leads to confusion. Only surgical exploration and histologic examination allow to make the right diagnosis and then adjust a best management of this disease.
