Figure 2.

Axial STIR (top, though with incomplete fat suppression) and axial T1W images through the calves showing various changes. There are changes within the medial heads of both gastrocnemius muscles (short thick arrows) consistent with oedema, again with extension beyond the anatomical boundary of the muscle into the adjacent fascia. There are also some milder diffuse oedematous changes within the right soleus (thin arrow) and medial gastrocnemius muscles. No abnormal fatty changes were seen.
