Submucosal Uterine Fibroid

Description

Centered in the female pelvis, the uterus is rendered in cutaway to expose the endometrial cavity, surrounding myometrium, and the cervix tapering inferiorly into the upper vagina. A submucosal uterine fibroid (leiomyoma, myoma) bulges from the inner myometrium immediately deep to the endometrium, projecting medially into the uterine lumen rather than expanding outward toward the serosa. Bilateral uterine tubes extend laterally from the fundus toward the ovaries, which sit posterolateral to the uterus near the fimbrial ends. Spatial relationships are clear. Submucosal fibroids matter because their location distorts the cavity and disrupts endometrial function, which is why they are classically associated with heavy menstrual bleeding, intermenstrual spotting, and iron deficiency anemia out of proportion to overall uterine size. Even a relatively small intracavitary component can impair implantation and contribute to infertility or recurrent pregnancy loss, a distinction that drives management compared with intramural or subserosal leiomyomas. For procedural planning, this anatomic relationship is the point: hysteroscopic myomectomy targets the lesion from within the uterine cavity, and the depth of myometrial involvement correlates with operative complexity, fluid deficit risk, and the likelihood of staged resection. Use this artwork in gynecology and reproductive endocrinology teaching to contrast submucosal, intramural, and subserosal fibroid morphology, and in patient-facing counseling materials that explain why a “womb” mass can cause bleeding and fertility symptoms without external pelvic bulk. It also fits operative technique chapters illustrating hysteroscopy, sonohysterography, and FIGO submucosal fibroid classification concepts for journals and board review resources.
