Delayed onset muscle soreness (DOMS) - MRI findings

Case contributed by Dr Chris O'Donnell

Presentation

Thigh pain 48 hours post strenuous football training

Patient Data

Age: 14
Gender: Male

Diffuse oedema in the right rectus femoris muscle and to a lesser extent the left. All other muscles are normal.

Coronal scan shows extent of the oedematous change in the right rectus femoris - the patient's football kicking leg!

Case Discussion

The diffuse muscle oedema is a manifestation of exercise-induced microtrauma to muscle producing the clinical syndrome of DOMS (delayed onset muscle soreness). This should be contrasted with the rapidly appearing transient T2 signal change seen in muscles immediately after exercise that can be used to study the patterns of muscle activation for specific activities such as football kicking.
