📌 Focal Periphyseal Edema (FOPE)

• Focal regions of high signal on fluid-sensitive sequences adjacent to the proximal tibial physis indicate focal periphyseal edema (FOPE). 
• This phenomenon occurs at stereotypical sites of early physiologic growth plate closure, such as the distal physis of the femur and the proximal physis of the tibia. 
• FOPE represents a normal physiologic process of physeal fusion.

 

📌 Differential Diagnosis

✅ Growth Disturbance

• Growth disturbances can result in focal bridges and diffuse premature growth plate closure, which are the end results of permanent growth plate injuries. 
• Radiography should not be used for these cases as it often overestimates the true size of the bridge in more than one-third of cases. 
• These pathological bridges should not be confused with FOPE, which occurs at stereotypical sites of early physiologic growth plate closure. 
• Large bridges with fatty marrow are best depicted on T1-weighted MR images, while small bony and fibrous bridges often show variable signal intensity. 
• Tiny bridges may be revealed due to adjacent bone marrow edema, which forms in response to focal decreased flexibility at the site of tethering.

 

✅ Focal Physeal Widening

• Focal physeal widening, also known as physeal stress injury, manifests as a focal T2 hyperintense tongue-shaped widening of the physis on MR images. 
• This condition is pathologically similar to “gymnast wrist” and “little leaguer shoulder” and necessitates immediate temporary cessation of the causal sports activity.
