Ovarian cysts are not a diagnosis of disease, but are usually detected by ultrasound as an abnormality of the ovary, manifesting as a cyst that may look different on ultrasound as anechoic, moderate echogenic, hypoechoic, or strong echogenic. Some ovarian cysts are physiological, such as ovulation and post-ovulatory corpus luteum production in the ovary every month. In general, physiological cysts do not require surgical intervention, and most physiological cysts will disappear after 3 menstrual cycles of follow-up if the presence of a cyst is unintentionally detected by ultrasound. These cysts usually appear as non-echoic on ultrasound. Some ancillary tests, such as blood CA125, can also suggest the diagnosis of benignity and, if normal, are generally reassuring. Some exceptions: if an echogenic cyst is found on the ovary before menarche or after menopause, it is often abnormal and needs to be alerted to the possibility of a tumor and requires aggressive intervention. There are many causes of pathological cysts, the most common being benign tumors of ovarian origin, such as ovarian mature teratomas, and others such as endometriosis cysts. Regardless of the nature of the cyst, all pathological cysts should be surgically diagnosed and intervened. Currently, laparoscopic surgery is a minimally invasive surgical procedure that can diagnose and treat patients very well. The postoperative recovery is quick and less painful. Some ovarian cysts, if combined with moderate echogenicity and if they suggest a blood flow signal, need to be alerted to the possibility of being malignant. Of course physical examination, some blood CA125 tests can also help to suggest the diagnosis preoperatively. If malignant cysts are suspected, laparoscopic surgery is not indicated to avoid the spread of the tumor.
