What does uterine effusion in the hyperechoic area of ​​the uterine cavity mean?

Uterine effusion in the hyperechoic area of ​​the uterine cavity usually refers to abnormal echoes and fluid accumulation in the uterine cavity during ultrasound examination, which may be related to physiological changes, endometrial lesions, pregnancy-related conditions, infection and other factors. It is recommended to combine clinical symptoms and further examination to confirm the diagnosis.

1. Physiological changes

Transient uterine fluid accumulation may occur after ovulation or during the luteal phase of the menstrual cycle, manifesting as a small hyperechoic area and usually without accompanying symptoms. This kind of situation does not require special treatment. It is recommended to review the ultrasound after 1-2 menstrual cycles to observe changes to avoid excessive anxiety.

2. Endometrial polyps

Polyps formed by endometrial hyperplasia appear as hyperechoic masses under ultrasound, which may hinder the discharge of menstrual blood and cause uterine fluid accumulation. It is often accompanied by symptoms such as increased menstrual flow and prolonged menstrual period. The diagnosis requires hysteroscopy, and treatment options include levonorgestrel sustained-release intrauterine system or hysteroscopic polypectomy.

3. Residues of miscarriage

After pregnancy is terminated, the residue of pregnancy products may appear as a mixed echo mass with fluid accumulation in the uterine cavity, which may cause persistent vaginal bleeding and lower abdominal pain. The blood HCG level needs to be tested to assist in judgment. Treatment includes motherwort granules to promote uterine contraction, or uterine curettage to remove residual tissue.

4. Endometritis

Endometrial inflammation caused by pathogenic infection can lead to the accumulation of uterine cavity exudate, and ultrasound can show uneven high echo with fluid accumulation. Patients often present with fever and abnormal vaginal discharge. The secretions need to be cultured, and cefixime dispersible tablets combined with metronidazole tablets are used for anti-infective treatment as directed by the doctor.

5. Endometrial cancer

Necrosis and bleeding of malignant tumor tissue can form hyperechoic lesions combined with bloody effusion in the uterine cavity, which is more common in postmenopausal women and manifests as irregular vaginal bleeding. Diagnosis relies on curettage and pathological examination, and treatment requires total hysterectomy combined with radiotherapy and chemotherapy according to the staging.

When abnormal echoes and fluid accumulation in the uterine cavity are found, menstrual cycle characteristics should be recorded to avoid strenuous exercise that aggravates the risk of bleeding. It is recommended to improve the detection of tumor marker CA125 and prohibit self-administration of blood-activating drugs. Keep your vulva clean, choose pure cotton underwear and change it daily. If you have fever or increased bleeding, seek medical attention immediately. It is recommended that review ultrasound be performed 3-7 days after menstruation is clear to reduce interference from physiological factors.
