In order not to over treat uterine leiomyoma and to avoid overlooking uterine leiomyosarcoma, a highly reliable diagnostic method has been thought. Occasionally, it is difficult to discriminate uterine leiomyoma from uterine leiomyosarcoma. Recently positron emission tomography/computed tomography (PET/CT) has been proved useful in assessing pelvic malignancies. We experienced a ...
