An intramural leiomyoma of the uterus is a common type of uterine fibroid that develops within the muscular wall of the uterus. These noncancerous growths can vary in size and may cause symptoms such as heavy menstrual bleeding, pelvic pain, pressure, frequent urination, and bloating. In some cases, intramural fibroids can affect fertility or pregnancy. Diagnosis typically involves a pelvic exam and imaging tests such as ultrasound or MRI.
