Adenomyosis: the endometrial mesenchyme and glands grow into the myometrium, with clinical manifestations of dysmenorrhea and increased menstrual flow, and hyperechoic punctate blood flow signals in the uterus seen on ultrasound. 2. Endometrial polyps: endometrial polyps are strips of tissue formed by the proliferation of endometrial tissue, clinical manifestations of abnormal uterine bleeding, ultrasound is often manifested as a strip of echogenic signals in the uterine cavity. The first choice is hysteroscopy and curettage to exclude endometrial cancer and submucous fibroid tumor of the uterus. 3. Residual pregnancy in the uterine cavity after abortion: when abortion is not clean, there is still bleeding in the vagina, and ultrasound suggests that there is residual hyperechoic blood signal in the uterine cavity. It is recommended that women undergo regular gynecological examination and consult a professional doctor for professional treatment if any abnormality is found.
