๐ง Double Posterior Cruciate Ligament (PCL) Sign:
Double posterior cruciate ligament (PCL) sign results from meniscal material in the notch, inferior and parallel to the PCL in the same sagittal plane.
The intact ACL serves as a barrier, preventing further lateral displacement of the meniscal segment.
๐ฅ Mimics of the Double PCL Sign ๐ฅ:
- (Fig 1-A.05) Lateral Meniscus posterior root
- (Fig 1-A.11) Meniscofemoral ligaments (Humphrey ligament)
- (Fig 1-A.17) Oblique meniscomeniscal ligament
- (Fig 1-A.17) Oblique meniscomeniscal ligament
๐งฉ Double Anterior Horn Sign:
The double anterior horn sign is presented as two adjacent triangular seemingly anterior horns on a sagittal image.
The anterior triangle represents the normal anterior horn, while the posterior triangle represents the displaced bucket handle segment.
