This site needs JavaScript to work properly. NIH The most common cyst, endometrioma (n = 7), did not exhibit acoustic streaming in any case (Figure 2). typically contains uniform low-level internal echoes with a hypervascular wall on Doppler ultrasound. Endometriomas occur when ectopic endometrial tissue implants enlarge and repeatedly hemorrhage in response to hormonal stimulation, forming cystic lesions commonly on the ovaries. Hemorrhagic ovarian cysts typically develop as a result of ovulation.
