Endometriosis B-ultrasound manifestations, these characteristics are very obvious

If a woman has endometriosis, it can be detected through B-ultrasound examination, so it is best for women to have a detailed physical examination before becoming pregnant to understand their physical condition. So what are the manifestations of endometriosis on B-ultrasound?

1. Can endometriosis be detected by B-ultrasound?

Women of childbearing age with a history of progressive dysmenorrhea and/or infertility, who may be initially diagnosed with endometriosis if a tender nodule is palpated in the pelvic cavity or an inactive cystic mass next to the uterus during a gynecological examination. Ultrasound, CT and MRI are mainly suitable for patients with endometriosis cysts.

Endometriosis can cause menstrual abnormalities. Symptoms of endometriosis include:

1. Ectopic pregnancy: The ectopic endometrium can cause pelvic adhesions and obstruction of the fallopian tube. The fertilized egg can only implant and develop locally, which increases the probability of ectopic pregnancy.

2. Abnormal menstruation: Patients with endometriosis often experience shortened menstrual cycles, increased menstrual flow, or prolonged menstrual periods, indicating that the patients have ovarian dysfunction. Irregular menstruation can be used as a diagnostic reference, but it has no value in differential diagnosis.

2. What are the causes of endometriosis?

1. Implantation Theory

Menstrual blood flows backwards and endometrial implantation occurs. During the menstrual period, menstrual blood flows downstream from the cervix and vagina. However, a small amount of menstrual blood or other reasons mixed with shed endometrial fragments flow into the abdominal cavity through the fallopian ducts and implant on the surface of the pelvic organs to form endometriosis lesions.

2. Metaplastic endometrium

Serosa epithelium, metaplastic intima. During the human embryonic development period, the ovarian surface epithelium, peritoneum, vaginal rectal diaphragm, and umbilicus are all derived from the metaplasia of the body cavity epithelium. These tissues can be transformed under the stimulation of gonadal hormones, inflammation, and mechanical factors to form another type of tissue, which can also metaplasia into the endometrium.

3. Benign metastasis

Hematolymph, benign metastasis. This is a relatively rare cause of the disease. Endometriosis that occurs in the lungs, meninges, pericardium, limbs, and other distant parts is caused by the transfer of endometrial debris through the blood circulation or lymphatic system and retention in certain organs or tissues.

3. Can B-ultrasound detect endometriosis?

The diagnosis of endometriosis mainly relies on its clinical manifestations, physical signs and some auxiliary means, which mainly include B-ultrasound, laparoscopy, as well as CA125 and CA199. Among them, B-ultrasound is widely used in gynecological diseases because it has unique advantages in judging the nature of masses, and it is inexpensive, simple, convenient, safe and radiation-free. Endometriosis mainly occurs in the ovaries, also known as ovarian chocolate cysts, and has its own unique characteristics on B-ultrasound. Therefore, B-ultrasound is very helpful in the diagnosis of endometriosis.
