Free fluid in the pelvis means there is some fluid buildup in this area, which is common in women of reproductive age due to ovulation and the normal hormonal changes of the menstrual cycle. In these cases, free fluid in the pelvis is usually considered a normal finding.
However, free fluid in the pelvis can sometimes be related to conditions such as pelvic inflammatory disease, ascites, a ruptured ectopic pregnancy, or the presence of an abscess or hematoma. It can also happen after trauma or injury to organs in the abdomen or pelvis.
This fluid usually collects in an area called the pouch of Douglas, which is located near the cervix and is the lowest part of the abdominal cavity. Make sure to follow up with your gynecologist or the provider who ordered the test to discuss results.
