During an ultrasound, if it shows an echogenic area, it means it is fluid and may be a cyst, such as a luteal cyst, a gestational sac in early pregnancy, or a follicle, all of which will show as an echogenic area. Echoes mostly refer to solid masses, or cystic masses, such as uterine fibroids, chocolate cysts, teratomas, calcified foci or tumors. If there is a solid mass, it is important to observe it and review the ultrasound regularly. If the mass is large, promptly undergo surgery and have a pathological examination to clarify the nature of the mass. If the pathological examination determines that it is a malignant tumor, radiotherapy or chemotherapy can be taken after surgery. Most of the echogenic areas are physiological, and most of the echogenic areas are tumors or calcified foci, etc.
