PCL Mucoid Degeneration-MRI

We present a case of mucoid degeneration of the posterior cruciate ligament (PCL) in a 50 year old who complained of knee joint pain on flexion. Magnetic resonance imaging (MRI) showed a diffusely thickened PCL with increased signal intensity on the T1 weighted sequence. A few intact fibers were observed with continuous margin from origin to insertion. Contour of the ligament is maintained.  MRI of  mucoid degeneration of the cruciate ligament can be mistaken for those of partial tear of the ligament.
