Your provider may do any of the following to find out if you have a corpus luteum cyst:
- Imaging. These types of cysts often show up during ultrasounds. A transvaginal ultrasound allows your provider to take a closer look at your uterus and ovaries. During the procedure, a delicate wand that releases sound waves is inserted into your vagina. Once inside, it pulses sound waves that register as a visual on a monitor. It allows your provider to see any masses, like a corpus luteum cyst.
- Tests. Occasionally, your provider may check your hormone levels to characterize a cyst.
