The difference between uterine fibroids and cysts

Uterine fibroids and cysts are two different gynecological diseases. The main differences lie in tissue origin, pathological characteristics and clinical manifestations. Uterine fibroids are benign tumors formed by the proliferation of uterine smooth muscle tissue. Cysts are mostly fluid-filled sac-like structures in the ovaries or fallopian tubes.

1. Organizational source

Uterine fibroids originate from the smooth muscle cells of the myometrium and are solid tumors with a hard texture. Cysts mostly occur in the ovaries or fallopian tubes. They are fluid masses formed by abnormally expanded glands or tissues, and the contents are mostly serous or mucus fluid.

2. Pathological characteristics

The cut surface of uterine fibroids has a swirl-like structure with clear boundaries, which can be single or multiple. Spindle-shaped smooth muscle cells can be seen under the microscope. The cyst wall is thin and smooth, and there is no substantial tissue in the inner wall. Ultrasound examination shows an echoless area, and septa or papillary protrusions can be seen in some cysts.

3. Clinical manifestations

Common symptoms of uterine fibroids include increased menstrual flow, prolonged menstruation, and a feeling of bloating in the lower abdomen. Larger fibroids may press on the bladder or rectum. Most ovarian cysts are asymptomatic, but some may cause lower abdominal pain and menstrual disorders. If the pedicle is torsion or rupture, it may cause acute abdomen.

4. Imaging performance

In ultrasonography, uterine fibroids appear as hypoechoic masses with rich blood flow signals and may be accompanied by calcifications. The cyst appears as a round echoless area with enhanced echo at the rear. The diameter of functional cysts is usually less than 5 cm. Pathological cysts may have wall nodules or solid components.

5. Treatment principles

Asymptomatic uterine fibroids can be observed regularly. Those with obvious symptoms can be treated with mifepristone tablets, Guizhi Fuling capsules and other drugs, or undergo uterine myomectomy. Physiological cysts mostly resolve spontaneously, while pathological cysts require laparoscopic cyst removal or radical surgery depending on their nature.

It is recommended to undergo regular gynecological examinations, especially if symptoms such as abnormal vaginal bleeding and persistent abdominal pain occur, prompt medical treatment is required. Maintaining a regular daily schedule, avoiding high estrogen food intake, and exercising moderately can help maintain endocrine balance. Ultrasound examination is the first choice method to identify the two types of diseases, and the diagnosis needs to be combined with pathological examination.
