Consider the possibility of luteal cysts in the right ovary, referring to the possibility that a woman has physiological cysts. A woman’s ovary should not have cystic structures present except for the growth and development of follicles to exclude them. However, in some cases, the growth and development of the female follicle is not normally excluded, such as when the female has inflammatory diseases of the ovary, excessive thickening of the ovarian envelope, chocolate cysts, etc., which can cause the female follicle to continue to grow after maturation and develop into a corpus luteum cyst. Luteal cysts in women are relatively small, mostly less than 5 cm, with very good internal sound transmission, and patients do not have clinical discomfort such as abdominal pain, bloating or abnormal bleeding. No treatment is needed, patients need to review the ultrasound regularly for 3-6 months, and the review must be done after menstruation, not during the luteal phase after ovulation.
