What is the reason for uneven echo of the uterine myometrium?

A woman's uterus may develop many diseases. In addition to some inflammations, uterine fibroids, endometritis, etc. are all diseases that are very harmful to women's health. Therefore, women must learn to protect their uterus. In addition, they need to have regular physical examinations to understand the health of the uterus. If the examination finds that the echo of the uterine muscle layer is uneven, what may be the cause?

First, what is the uneven echo of the uterine muscle layer?

The uneven echogenicity of the myometrium suggests the possibility of adenomyosis, a type of endometriosis characterized by progressive dysmenorrhea and increased menstruation.

Second, what does uneven echo of the uterine myometrium mean?

The uterus was posteriorly located, with a body size of approximately 4.0x3.6x4.4cm and uneven echogenicity: the uterine cavity line was centered, the endometrial outline was unclear, and the thickness was approximately 0.6cm: an irregular liquid dark area with a depth of approximately 1.2cm was seen in the rectouterine fossa; CDFI: no obvious blood flow signal was seen in the bilateral adnexa of the uterus.

Uneven echo of the myometrium can be seen in a variety of uterine diseases, but it is generally considered to be adenomyosis. Uneven echo of the myometrium is the invasion and spread of the endometrium into the myometrium. This disease is more common in women aged 30-50 and is often accompanied by progressive dysmenorrhea. There are three main possibilities for uneven echo of the uterine muscle layer. The first is the misdiagnosis caused by the mistake of the doctor doing the B-ultrasound. The second is that if the B-ultrasound is done when the menstruation is about to come, it may also be uneven. At that time, the uterus is congested. You can do another one immediately after the menstruation is over to see if it is still uneven. The third is that there may be some endometriosis.

Third, what is the uneven echo of the uterine muscle layer?

Myometrial hypoechoicity is an ultrasound term. There are many reasons. One may be caused by uterine fibroids, adenomyosis, endometriosis and other diseases. The description is incomplete and cannot be specifically diagnosed. Endometriosis can cause progressive dysmenorrhea during menstruation. The second reason is due to ultrasonic technology and instruments, which is generally described like this. If you don't have any symptoms, don't worry and go to the hospital for regular follow-up.

Fourth, the causes of endometrial thickening and uneven echo

B-ultrasound examination found that the endometrium was thickened and the echo was uneven. There are several reasons for this:

1. Endometritis

Ultrasound reveals that endometrial thickening and uneven echoes are mostly caused by endometritis. The main clinical manifestations of endometritis are lower abdominal distension, lumbosacral pain, increased or bloody leucorrhea, increased menstrual flow, and dysmenorrhea.

2. Endometrial hyperplasia

It is an abnormal proliferation of endometrial glands and stroma. It is a benign lesion. The endometrial thickening can reach 3 to 25 mm. It is more common in puberty and menopause, including simple hyperplasia, cystic hyperplasia, adenomatous hyperplasia, and atypical hyperplasia. Common symptoms include irregular uterine bleeding, menstrual cycle disorders, heavy menstrual flow, shortened or significantly prolonged menstruation. B-ultrasound shows uniform thickening and symmetry of the endometrium, with the uterine cavity line centered. In atypical hyperplasia, the endometrial echo is uneven, with alternating plaques and low echoes.

3. Endometrial polyps

Endometrial polyp is a pedunculated tumor-like lesion formed by localized proliferation and protrusion of endometrial glands and fibrous stroma, but it is not a true tumor. It is more common in women aged 40 to 50. Its main clinical manifestations are increased menstrual flow, prolonged menstrual period, increased leucorrhea, postmenopausal uterine bleeding, etc. It may also have no obvious symptoms and be discovered during physical examination. When single, B-ultrasound shows an inhomogeneous low-echo or high-echo mass in the uterine cavity, which is clearly demarcated from the normal endometrium. When there are multiple polyps, the intima is thickened and has uneven echoes. Irregular clusters of high-echo spots are seen in the intima, and the boundary between the intima and the normal intima is unclear.

4. Endometrial cancer

It is a group of epithelial malignant tumors that occur in the endometrium. It is one of the three most common malignant tumors in women. 80% of them occur in postmenopausal women, with endometrial adenocarcinoma being the most common. The peak age is 50 to 60 years old, most of whom are postmenopausal. There may be no symptoms in the early stage, and the main manifestations are irregular uterine bleeding, postmenopausal uterine bleeding, and increased leucorrhea. In the late stage, it may manifest as lower abdominal pain and systemic symptoms. B-ultrasound shows uneven echoes in the uterine cavity, thickened endometrium with uneven echoes, and when the tumor invades the myometrium, the uterus becomes enlarged and deformed, with unclear contours.
