Pedunculated Subserosal Fibroid In An Anterior Section Of The Uterus

Description

Uterine serosa and myometrium are cut in an anterior section that exposes the uterine cavity and outer fundal contour while keeping the external surface in the same frame. A pedunculated subserosal fibroid (leiomyoma) projects from the uterine surface, connected by a narrow stalk of tissue that arises from the superficial myometrium beneath the perimetrium. The mass sits superficial to the endometrium, with its bulk oriented away from the cavity and its attachment point clearly separated from the endometrial lining. Stalk anatomy is the focus. Pedunculated subserosal leiomyomas matter because their symptoms and risks differ from intramural or submucosal fibroids: they often present with pressure on adjacent pelvic organs rather than abnormal uterine bleeding, and the thin pedicle can twist, producing acute pelvic pain and ischemic degeneration that may mimic adnexal torsion. For operative planning, the anterior sectional perspective helps you judge the relationship of the stalk to the uterine wall thickness and serosal surface, a practical distinction when counseling patients on laparoscopic myomectomy versus hysterectomy and when anticipating serosal repair and hemostasis at the pedicle base. The spatial separation between the fibroid and endometrial cavity also reinforces why hysteroscopic access is typically not appropriate for subserosal pathology. Use this illustration in gynecology lectures on uterine fibroid classification, in board-style question banks contrasting subserosal, intramural, and submucosal disease, and in patient-facing materials explaining why a surface fibroid can cause bulk symptoms without heavy bleeding. It also suits surgical education modules on pedicle ligation, differential diagnosis with adnexal masses on pelvic imaging, and pathology captions pairing “uterus, subserosal leiomyoma, stalk” with operative findings.
