Hemorrhagic ovarian cysts are a common cause of acute pelvic pain in young women. They are typically caused by a ruptured blood vessel within the cyst. The ultrasound imaging findings of a hemorrhagic ovarian cyst can vary depending on the stage of bleeding.
Ultrasound imaging findings of hemorrhagic cysts:
In the early stages of bleeding, the cyst may appear as a simple cyst with an echogenic rim. As the bleeding progresses, the cyst may become more heterogeneous with internal echoes. The echoes may have a lace-like or reticular appearance, which is sometimes described as a "fish net" pattern.
In some cases, the cyst may contain a solid clot. The clot may be mobile or attached to the cyst wall. The cyst wall may be thickened and irregular.
Differential diagnoses:
The ultrasound imaging findings of a hemorrhagic ovarian cyst can be similar to those of other conditions, such as an ovarian neoplasm or an ectopic pregnancy. Therefore, it is important to obtain a complete clinical history and perform other imaging tests, such as a pelvic CT scan or MRI, to confirm the diagnosis.
The treatment of a hemorrhagic ovarian cyst depends on the size and severity of the bleeding. In most cases, the cyst will resolve on its own without treatment. However, if the cyst is large or causing significant pain, it may need to be surgically removed.
