A uterine lipoleiomyoma is a variant of uterine rnyomas, however, it is rarely found in patients and the diagnosis of uterine lipoleiomyoma has always been in retrospect. Uterine lipoleiomyomas are often diagnosed preoperatively as uterine myomas or ovarian mature teratomas. The key to distinguishing the tumors from lipoleiomyomas is to ascertain the primary site of development - uterus or adnexa. When a large uterine tumor is found in a postmenopausal woman, the possibility of malignancy should be considered Now, however, advanced modern imaging systems can provide more precise diagnoses than before. The following case illustrates how a uterine lipoleiomyoma was highly suggestive preoperatively based on typical characteristics on ultrasound and computed tomography (CT). A homogeneous hyper-echoic mass confined to the uterus on ultrasound initiated the suspiction of the tumor. In addition, the uterine mass showed lower density than water on CT which further established the possibility of a fatty tumor of the uterus. The final pathological examination results confirmed the diagnosis of lipoleiomyoma.
