Abstract:
Among the MRI signs of meniscal bucket handle tears, a double posterior cruciate ligament (PCL) sign manifests on the sagittal images as a low signal band anterior and parallel to the PCL. The mesially displaced fragment may be confined to the intercondylar notch. However, the torn fragment is rarely displaced to the posterosuperior region of the PCL. If it does occur, separation at the anterior horn may be assumed. We propose this type of lesion be called the posterior double PCL sign in contrast to the ordinary double PCL sign. We present a case showing the 'posterior double PCL sign' accompanying an anterior cruciate ligament injury.
