ITB ILIOTIBIAL BAND FRICTION SYNDROME MRI

TWO POSSIBILLITIES

With fluid deep to the ITB we have 2 possibilities. 

• • It’s a recess of the suprapatellar bursa or,

• • It’s an ITB bursa (an adventitial bursa which develops due to friction).

HOW DOES THE ANATOMY HELP TO DIFFERENTIATE?

• ITB BURSA will NOT communicate with the suprapatellar recess or supraptellar bursa .

• SUPRAPATELLAR RECESS will communicate with the joint via the suprapatellar bursa.

MRI HOW DO YOU DIFFERENTIATE THEM

• Follow the axial scans from superior to inferior.
• See if you can spot any communication between the the fluid and the suprapatellar bursa/recess.
• If you can’t see any communication it’s an ITB bursa.

THE TAKE AWAY

• You can confuse a normal supra patellar recess with an ITB bursa.

• But the recess will communicate with the joint and the ITB bursa won’t.

• On axial scans look for communication between joint/ recess and the fluid collection.
