What is theca lutein cyst ultrasound?

A theca lutein cyst is a type of ovarian cyst that develops due to hormonal changes in the body. It may be detected during an ultrasound exam of the pelvic area. Theca lutein cysts appear as thin-walled, multiloculated cysts with echo-poor or echo-rich contents, depending on the presence or absence of hemorrhage or proteinaceous fluid. These cysts typically resolve on their own after several weeks or months. However, if the cyst is large or causing symptoms, further evaluation and management may be necessary. A healthcare provider may perform additional tests or imaging studies to rule out other conditions and determine the appropriate treatment plan.
