Uterine lipoleiomyoma are rare benign tumors consisting of smooth muscle and mature adipose tissue. Because of their rarity, fat content, and variable gross morphology, they may be mistaken on radiodiagnosis for the much more common benign cystic ovarian teratoma. The key to differentiate these lesions is the identification of the organ of origin. A mass that arises from the uterus is most likely a lipomatous uterine tumors. Because malignant degeneration occurs in 1-2% of benign cystic ovarian teratomas, their differentiation can be clinically significant. While these tumors are treated by surgical excision, asymptomatic lipomatous uterine tumors and benign pelvic lipomas may require no therapy. The fatty nature of the lipoleiomyoma was demonstrated with standard spin-echo Magnetic resonance imaging (MRI) and further supported using fat- suprressed inversion recovery MRI. MRI also clearly depicted the intrauterine location of the tumor. We report a case in which a preoperative diagnosis of a uterine lipoleiomyoma was made with MRI and fat suppressed MRI.
