Intramural uterine leiomyoma is the most common type of uterine leiomyoma in terms of location. They are centered primarily within the myometrium. A large intramural uterine leiomyoma can, however, have a submucosal or subserosal component.
They are usually asymptomatic; however, they may cause infertility due to compression of the fallopian tubes.
These may also occasionally cause bleeding which may be due to interference of intramural leiomyomas with normal uterine contractility.
