MRI DELAMINATION ROTATOR CUFF TEARS & MRI MUSCULOTENDINOUS JUNCTION CYSTS

On MRI Rotator cuff delaminating tears can result in Musculotendinous Junction Cysts.

 

These Musculotendinous junction cysts are seen in the rotator cuff tendons, mostly in Supraspinatus and less commonly in infraspinatus.

 

In this post we look at the appearance of both Delaminating Rotator cuff tears and Musculotendinous junction cysts.

MRI DELAMINATING ROTATOR CUFF TEARS & MUSCULOTENDINOUS JUNCTION CYSTS
  • MTJ cysts area result of an underlying articular surface delaminating tear.
  • The tear extends through the tendon and when it gets to the MTJ, is arrested.
  • Fluid keeps accumulating in the tear which wells up at the MTJ to form a cyst.

Centered at the MTJ, but if large can extend into the tendon and muscle.

  • Can be single or multiple cysts (Pink arrows).
  • Usually not septated and no enhancement.
  • May see connecting delaminating tear (Blue arrows).

Here is what to look for when assessing MTJ cysts.

 

  1. Location (which tendon) of cyst/s.
  2. Size of cyst/s.
  3. A delaminating tear extending to the cyst.
