Fluid Collections around the Posterior Cruciate Ligament

Fluid collections behind the posterior cruciate ligament (PCL) are often ganglion cysts. However, there are two other fluid collections that can mimic a PCL ganglion cyst: a pericruciate meniscal cyst (related to a posterior horn medial meniscus tear) and fluid in the PCL recess.1,2

Features of a Pericruciate Meniscal Cyst²

• Communicates with tear of posterior horn medial meniscus
  
• Centered on PCL: a ganglion cyst is usually at the femoral or tibial PCL insertion
  
• May surround PCL
