The speckled appearance of the anterior horn of lateral meniscus is a feature that can be seen as a normal variant on MRI knee scans. It is usually seen near the lateral meniscus central attachment site. It is often explained by fibers of the anterior cruciate ligament and the covering synovium inserting into the meniscus root giving it a striated appearance.
