The Calcaneofibular ligament is a small lateral ankle ligament that is often torn.

Here is what to look for when assessing for an acute tear of the Calcaneofibular ligament on MRI.

  • Thickened, hyper-intense and ill defined calcaneofibular ligament (Pink arrows).

 

  • This can involve the entire ligament or  a portion of it.

 

  • The anatomical landmark to find the CFL are the Peroneal tendons (Blue arrows) with the CFL lying deep to it between the peroneal tendons and calcaneum.
