Iliotibial Band Syndrome-MRI

Patient presented with pain on the lateral aspect of knee, no injury. 

Findings: Multilobulated cystic areas in the lateral recess deep to the iliotibial band along with focal discontinuity in the tract with communicating fluid space superficial to the band. Thickening of the tibial insertion of iliotibial band on the gerdy tubercle and there is reduced space between the distal iliotibial tract and lateral femoral condyle. These findings likely suggest iliotibial band friction syndrome with associated bursal cyst and possible discontinuity in the band. 

Discussion : When the knee flexes, the ITB moves posteriorly along the lateral femoral epicondyle. When the band is excessively tight or stressed, the ITB rubs against the epicondyle irritating the lateral synovial recess.
