A vaginal ultrasound is performed to examine the patient’s uterine body, cervix, endometrium, and the patient’s bilateral ovarian fallopian tubes. If the vaginal ultrasound shows echogenic heterogeneity, it mainly refers to the woman’s endometrium and uterine body. The exact cause of this heterogeneous echogenicity needs to be determined by combining the patient’s clinical symptoms and signs, as well as the comprehensive hints of the patient’s ultrasound. If the echogenicity of the endometrium is heterogeneous, accompanied by abnormal thickening of the endometrium or dotted strong echogenicity, the patient may have endometrial inflammation, endometrial adhesions or endometrial polyps, and most patients have clinical manifestations such as abdominal pain or irregular vaginal bleeding. If the echogenicity of the myometrium is heterogeneous, inflammation of the myometrium or adenomyosis will be considered.
