What does the left ovarian echoless area mean?

The anechoic area of ​​the uterus and ovaries refers to the abnormal proliferation of tissue in the uterus and ovaries that can be seen under ultrasonic monitoring. The outer membrane is relatively detailed and contains fluid. There are two reasons why the uterine and ovarian echo-free areas may result. The first is physiological changes, such as enlarged eggs, corpus luteum cysts or follicular cysts. If this is the case, most patients do not have significant lower abdominal discomfort and no menstrual changes. After 3-6 months of observation, the ultrasound was repeated and most of them had disappeared automatically.

Physiological changes, such as uterine and ovarian tumors, whether they are plasma tumors or mucinous tumors, all show echo-free changes under ultrasound monitoring. Such conditions require follow-up examination for relevant uterine and ovarian tumor markers. In addition, observation or surgical treatment is adopted depending on whether the patient has clinical manifestations.

The uterus and ovaries have no echo area, which may be an egg or a cyst. Because it is an ultrasound examination, the sound wave frequency encounters different parameters and can be reflected back to be displayed on the screen. If the page density encountered is extremely low, a no-echo zone will appear. It is necessary to look at the size and range of the anechoic zone to determine whether it is a pathological condition. It is also necessary to integrate clinical manifestations for comprehensive differentiation. If it is an ovarian cyst, cystic echo may appear. If the echo-free area is relatively small, it may be a normal egg.

The echo-free area of ​​the uterus and ovaries under ultrasound should be analyzed in combination with the physiological cycle. If there is an echo-free area of ​​the uterus and ovaries before and after ovulation, it is likely to be an egg depending on the number. If the echo-free zone does not exceed 20 mm before ovulation, it should be the egg. If the echo-free zone is after ovulation, it may be that the egg has not been released. It is recommended to have a follow-up ultrasound after 2 months to see if the echo-free zone is still there. If the egg has not been released, it will not be seen after 2 months. If the echo-free area still exists after 2 months, it may be an ovarian cyst. It is recommended to check the tumor markers and conduct a comprehensive analysis.
