What does it mean when an MRI reports Intrasubstance high signal is seen within the anterior horn and body of lateral meniscus?

Intrasubstance high signal is seen within the anterior horn and body of lateral meniscus usually means that there is a tear in the meniscus. The meniscus is a piece of cartilage that helps to cushion the knee joint. When the meniscus is torn, it can cause pain, swelling, and stiffness in the knee.

An MRI (magnetic resonance imaging) scan can be used to diagnose a meniscus tear. An MRI scan uses a magnetic field and radio waves to create detailed images of the inside of the body. On an MRI scan, a meniscus tear will appear as a high signal area within the meniscus.

The location of the tear is also important. Tears in the anterior horn and body of the lateral meniscus are more common than tears in other parts of the meniscus. Tears in the anterior horn and body of the lateral meniscus can be treated with surgery or with conservative measures, such as rest, ice, and physical therapy.
