When the ovarian cyst is an echogenic cyst it generally refers to a simple ovarian cyst, while a non-echogenic cyst is generally not a simple cyst. There are differences between the two in terms of etiology, diagnosis and treatment modalities: 1. Echogenic cyst: the fluid within the cyst is clearer and is a more common simple cyst, usually indicating that there is fluid accumulation within the cystic mass. This situation may be physiological ovarian cysts, which can be observed, if the cysts do not disappear, it is necessary to take corresponding treatment for cysts of different sizes: 1, diameter less than 5cm: often considered physiological ovarian cysts, most of which can automatically shrink or disappear, but may also recur in the same ovary or grow on the other side of the ovary, in general, there is no need to worry too much, but should go to the regular hospital every 3 months In general, there is no need to worry too much, but you should go to a regular hospital every 3 months to review the ultrasound; 2. Diameter greater than 5 cm: complications such as rupture, infection and torsion may occur, and surgery is usually recommended. Second, non-echoic cysts: usually suggest substantial cysts, but specific analysis of echogenic light spots is needed: 1. Fine echogenic light spots: consider chocolate cysts, i.e. endometriosis cysts. If the cyst is small and mild, medication and regular review can be performed to closely observe the changes in the condition of the ovary; when the cyst is large and poorly positioned, it is considered as surgical treatment; 2. Strong echogenic light mass: often considered as a mixed mass, which may be a teratoma or a substantial lesion within the cyst. At this time, ultrasound review of the ovaries is recommended after 3 months to pay attention to changes in the condition of the ovaries, and laparoscopic surgery can be done if necessary.
