Discoid meniscus

  1. Large meniscus: Lens-shaped, wedged, flat.
  2. Lateral meniscus (3% population) more commonly involved than medial.
  3. More prone to tear.
  4. Can be symptomatic even without a tear.
 
A discoid meniscus is seen as an abnormally wide body. Usually, the body of the lateral meniscus is only seen on two adjacent sagittal slices. A discoid meniscus can be diagnosed if it is seen on three or more standard sagittal images (the opposite of the absent bow tie sign).
