How does ultrasound determine a corpus luteum cyst?

Under B-ultrasound, a small cystic mass in the adnexal region adjacent to the uterus can be identified as a corpus luteum cyst. When the cyst is small, normal ovarian structure may be visible on one side. Most corpus luteum cysts occur unilaterally, with a diameter less than 3 cm, and generally do not require treatment. However, regular B-ultrasound examinations are necessary. These ultrasound examinations should be performed at a正规 medical facility. The specific procedure is as follows:

1. After sufficiently filling the bladder, the patient enters the examination room and assumes a supine position, exposing the abdomen as instructed by the physician.

2. During the examination, the doctor applies an appropriate amount of coupling agent to the patient's abdomen and the front end of the probe, then places the ultrasound transducer on the area to be examined. The patient should cooperate with the doctor in adjusting body position as needed.

3. During the examination, the patient may view the intrauterine condition together with the doctor. If a small cystic mass appears in the adnexal region beside the uterus, this indicates the presence of a corpus luteum cyst.

4. After the examination, the doctor provides tissues for wiping off the coupling agent and gives relevant instructions. The patient may then dress and leave the examination table.

In daily life, patients can make a preliminary self-assessment of whether they have a corpus luteum cyst based on their symptoms. Corpus luteum cysts may rupture, leading to internal bleeding and acute abdominal conditions. Patients with acute corpus luteum cysts may experience symptoms such as fever and abdominal pain, while those with chronic cases may feel dull lower abdominal pain or a sensation of heaviness and distension.
