RETROCALCANEAL BURSITIS RADIOLOGY MRI

  1. RETROCALCANEAL BURSITIS.
  2. ACHILLES TENDONOSIS.

  • The retrocalcaneal bursa lies anterior and deep to the Achilles tendon postero superior to the calcaneum.
  • The normal bursa has minimal fluid so on MRI you may see nothing or just a thin amount of fluid without synovial thickening.
  • For retrocalcaneal bursitis on MRI look for contained  fluid signal intensity in the expected location of the bursa.
  • In this case there is significant fluid in the bursa (Pink arrow) in keeping with bursitis.
  • The Achilles tendon is usually abnormal with tendonosis or tears. In this case, increased intermediate signal and expansion Achilles tendon (Green Arrow) in keeping with tendonosis.

  1. Fluid present anterior to the Achilles tendon ( Pink arrow).
  1. Increased intermediate signal and expansion Achilles tendon ( Green Arrow).
