Hypoechoic mass with clear borders visible in the left wall of the uterine fundus is likely to be the ultrasound imaging manifestation of uterine fibroids and ovarian cysts. 1. Uterine fibroids are a common disease in women. Around 30% of women are found to have fibroids, which usually shrink after menopause, so if they are asymptomatic, they often do not require surgical treatment. If there is a need for fertility, the doctor will need to carefully evaluate the fibroids before deciding what to do next. 2. Ovarian cysts with clear hypoechoic borders are mostly physiologic and do not require treatment if the ovaries are not large. You can go to the hospital for another ultrasound examination after your next menstrual period to make a clear diagnosis. If the ovarian cyst has exceeded 5 centimeters, it is recommended to operate as early as possible, and you can visit the hospital three to seven days after the menstrual period.
