An intracavitary fibroid (or leiomyoma) is a submucosal fibroid which lies completely within the endometrial cavity (FIGO type 0). Commonest presenting symptom is menorrhagia. They may also present with dysmenorrhea, infertility, or as a palpable mass on vaginal examination.

Hysteroscopic myomectomy is typically the preferred treatment for intracavitary fibroids. Uterine fibroid embolization is effective but carries an increased risk of fibroid expulsion, and potentially associated bleeding or sepsis.
