What Is a Hemorrhagic Cyst?

3. What Causes a Cyst to Develop?
In any given month the normal function of an ovary can be slightly altered, resulting in a change in ovulation or the actions that directly follow ovulation. After ovulation, a structure called a corpus luteum develops in the ovaries. This structure is very vascular.
Sometimes a small vessel breaks in the corpus or follicular luteum, and the blood is trapped inside a cyst. Although they are sometimes asymptomatic, hemorrhagic cysts are typically found on ultrasound after the patient complains of pain.
