It is generally inappropriate to use cystic echogenicity and anechoic echogenicity as criteria for differentiating severity. Cystic echogenicity and no echogenicity are two kinds of findings during ultrasound examination, which often suggest the occurrence of lesions in the body. Cystic echogenicity generally refers to occupying lesions with fluid-like changes in the border, i.e. substantial cysts or abscesses are shown under ultrasound, and no echogenicity generally refers to lesions with fluid-like changes in the border, i.e. fluid other than blood or bile is seen under ultrasound, such as pleural fluid, ascites, pericardial effusion, etc. 1, cystic echogenicity 1, physiological cystic echogenicity: physiological cystic echogenicity is usually seen in physiological cysts in the ovary, mostly occurring in the second half of women’s menstruation, which usually does not have too much impact on the body, and generally with the end of menstruation, physiological cysts in the ovary will also be significantly reduced or disappear; 2, pathological cystic echogenicity: pathological cystic echogenicity is mostly seen in a variety of parenchymal organ lesions, such as liver cysts, spleen cysts The cystic echogenicity can also appear in cystic lesions of the uterus. When pathological cysts are found, they should be treated in time to avoid delay or malignant transformation of the disease, and the main treatment method is surgery. 2, no echogenicity 1, physiological no echogenicity: when there is a female ovarian cyst will appear no echogenicity phenomenon, generally cyst diameter is less than 5cm, this may be normal follicles or filtering cysts, usually after the end of menstruation will disappear, can be reviewed after the end of menstruation ultrasound, to clarify the diagnosis; 2, pathological no echogenicity: pathological no echogenicity is mostly seen in pleural effusion, pericardial effusion, ascites, advanced cirrhosis, etc.. This situation needs to be treated according to the disease development and the patient’s own situation, and puncture treatment and anti-infection treatment etc. should be carried out under the doctor’s suggestion in order to actively treat the disease and prevent the aggravation of the disease. In case of cystic echogenicity or absence of echogenicity on ultrasound examination, the diagnosis of the disease should be confirmed promptly in combination with other examination contents, and then a reasonable treatment plan should be formulated for active treatment according to the patient’s condition and the doctor’s recommendation.
