Imaging Diagnosis of an Uterine Lipoleiomyoma, a Rare Entity

Resumo

Uterine lipoleiomyoma is a rare benign tumour arising from the myometrium, composed of smooth muscle cells and mature adipocytes. It is easily misdiagnosed preoperatively on radiological imaging studies as an uterine myoma or an ovarian mature teratoma. We report a case of a postmenopausal woman who presented with pelvic pain over the last 6 months. On gynaecological examination the uterus was enlarged with a painless nodular formation.

Findings on transvaginal ultrasound (US) and magnetic resonance imaging (MRI) raised the suspicion of an uterine lipoleiomyoma. The patient was operated on and the suspected diagnosis was confirmed by the histological examination. In this paper we report the typical ultrasonographic and MRI findings of an uterine lipoleiomyoma.
