A Pedunculated Subserosal Fibroid In An Anterior Section Of The Uterus

Description

Anterior uterine anatomy is opened in section to expose the endometrial cavity and surrounding myometrium, while the serosal surface (perimetrium) remains continuous at the outer contour. A pedunculated subserosal leiomyoma projects from the external uterine surface, connected by a narrow stalk that originates in the superficial myometrium and carries its vascular supply. Across the sequence, the fibroid’s attachment is clarified as extra-cavitary, sitting superficial to the myometrium rather than distorting the endometrium, with the stalk shown as the key anatomic bridge between tumor and uterine wall. Pedunculated subserosal fibroids often present less with menorrhagia and more with bulk symptoms, pressure effects on adjacent pelvic viscera, or acute pain when the stalk torses and compromises venous outflow. Torsion is the feared event. Animation helps by separating wall layers and tracking the stalk from serosa into the uterine wall, a relationship that can be hard to parse in a single frame and directly informs how you counsel patients and plan uterine-sparing surgery. Obstetrics and gynecology teaching modules can use this clip to contrast subserosal, intramural, and submucosal leiomyomas and to anchor discussions of FIGO leiomyoma types, degeneration, and symptom patterns. It also supports preoperative counseling and operative planning content for laparoscopic or open myomectomy, where identifying a pedunculated stalk and its feeding vessels guides safe ligation and reduces hemorrhage risk.
