The fundus of the uterus is the upper, rounded part of the uterus, opposite from the cervix. Masses in the fundus can arise from various tissues within the uterus and can affect a woman’s health in multiple ways. Understanding these masses— their causes, symptoms, diagnostic methods, and treatments—is essential for timely and effective medical care.
The fundus is the top part of the uterus, situated above the openings of the fallopian tubes. It’s dome-shaped and plays a crucial role during pregnancy as it expands to accommodate the growing fetus. Masses in this area can range from benign (non-cancerous) growths to malignant (cancerous) tumors.
Pathophysiology
Structure
The uterus is a muscular organ composed of three layers:
- Endometrium: The inner lining that sheds during menstruation.
- Myometrium: The thick, muscular middle layer responsible for contractions.
- Perimetrium: The outer serous layer.
Masses can develop from any of these layers or from surrounding tissues.
Blood Supply
The uterus receives blood primarily through the uterine arteries, which branch from the internal iliac arteries. Adequate blood supply is essential for uterine function and healing.
Nerve Supply
Nerve fibers from the hypogastric plexus provide sensory and autonomic innervation to the uterus, influencing pain perception and uterine contractions.
Types of Fundus Masses
- Fibroids (Leiomyomas): Benign smooth muscle tumors.
- Adenomyomas: Growths where endometrial tissue exists within the muscular wall.
- Endometrial Polyps: Benign overgrowths of the endometrial lining.
- Cystic Masses: Fluid-filled sacs, such as endometrial cysts.
- Malignant Tumors:
- Endometrial Carcinoma: Cancer of the endometrial lining.
- Leiomyosarcoma: Malignant smooth muscle tumor.
- Pregnancy-Related Masses:
- Ectopic Pregnancy: Pregnancy outside the uterus, sometimes in the fundus.
- Hydatidiform Mole: Abnormal fertilization leading to tissue overgrowth.
- Retained Products of Conception: Remaining placental or fetal tissue after birth or miscarriage.
- Metastatic Tumors: Cancers from other body parts spreading to the uterus.
