Peduncular Submucosal Uterine Fibroid

Description

Positioned in lateral section, the uterus is rendered with the myometrium forming the thick outer wall and the endometrium lining the uterine cavity as a paler mucosal layer. Projecting into the endometrial cavity sits a peduncular submucosal uterine fibroid (leiomyoma, myoma), attached by a narrow stalk to the underlying myometrium and displacing the cavity contour toward the fundus. Inferiorly, the uterine body tapers into the cervix with the endocervical canal leading into the vagina, providing clear orientation along the superior to inferior axis. Laterally, the uterine cornu suggests continuity with the fallopian tube toward the adnexa. Pedunculated submucosal fibroids matter because their intracavitary position, even when relatively small, distorts the endometrial surface where implantation and normal menstrual shedding occur. Expect abnormal uterine bleeding, iron deficiency anemia, and reproductive complaints, including infertility and recurrent pregnancy loss; in FIGO terms, these lesions often align with type 0 or type 1 submucosal myomas targeted via transcervical hysteroscopic myomectomy. A narrow pedicle also introduces a specific complication profile, including stalk avulsion during instrumentation and ischemic degeneration after torsion of the peduncle. Small details. They change management. Use this lateral uterine view in OB-GYN teaching on fibroid classification and procedural planning, and in patient-facing materials that explain why a submucosal myoma behaves differently from an intramural or subserosal lesion. It also fits well in surgical atlases, exam-prep resources, and publications discussing sonohysterography or hysteroscopic resection margins relative to endometrium and myometrium.
