Outer Growth of a Peduncular Subserosal Uterine Fibroid

Description

Centered in the pelvis, the uterus is drawn with its myometrium surrounding the endometrial cavity and tapering inferiorly into the cervix, which continues into the vaginal canal. Arising from the outer uterine contour, a pedunculated subserosal leiomyoma (uterine fibroid, myoma) projects externally beneath the serosa, connected to the uterine wall by a narrow stalk. Laterally, the uterine (fallopian) tubes extend toward the ovaries, with the adnexa positioned superior and lateral to the uterine fundus. The mass sits extra-cavitary and extra-endometrial by design. Peduncular subserosal fibroids matter because their growth pattern shifts the clinical problem from bleeding to bulk and acute pain. A narrow pedicle can twist, producing torsion with venous congestion and ischemic degeneration, a presentation that can mimic ovarian torsion or a complex adnexal mass on ultrasound. Surgeons also care about the stalk’s attachment site and vascular supply, since laparoscopic myomectomy or hysterectomy often begins with identifying the pedicle, controlling feeding vessels near the serosal surface, and avoiding collateral injury to the tube, ovary, or uterine vessels along the lateral uterus. Acute torsion can be dramatic. Use this artwork in gynecology teaching on leiomyoma classification (submucosal, intramural, subserosal), in radiology correlation pages explaining why a pedunculated subserosal myoma may be mistaken for an ovarian lesion, or in patient education materials that need clear distinction between uterine and adnexal pathology. It also fits operative consent documents and procedural guides discussing myomectomy approach and risk of recurrence or degeneration. Anatomical accuracy verified by SciePro's Medical Advisory Board.
