Sagittal proton-density–weighted fast spin echo images in a 43-year-old female patient through the lateral meniscus. At the insertion of the posterior meniscofemoral ligament (a), the ligament (large arrow) closely parallels the outer posterior margin of the posterior horn of the lateral meniscus (small arrow). The linear signal between the low-intensity meniscus and the low-intensity ligament may lead to pitfalls and could be confused with a detached meniscal fragment. However, on the next more medial sagittal image (b), the ligament (large arrow) is clearly visible posteriorly to the posterior cruciate ligament
