Uterine leiomyomas (fibroids) are the most common benign tumor of the female reproductive system. Fibroids can become symptomatic with symptoms such as menorrhagia and menometrorrhagia, pelvic pain, and reproductive dysfunction. Hysterectomy, myomectomy, and the less invasive uterine artery embolization are now commonly performed if conservative management of symptomatic fibroids fails. Moreover, uterine artery embolization (UAE) is the preferred minimally invasive procedure for the treatment of symptomatic fibroids. Major complications of UAE are extremely rare but well known. Additionally, there is a risk of undiagnosed uterine sarcoma found post embolization, which has been reported in literature during the past 12 years. Herein, we describe a case of an incidentally discovered uterine sarcoma in a premenopausal female after hysterectomy for post uterine artery embolization endometritis and sepsis.
