Part I: ankle and hindfootAccessory soleus. 36-year-old woman referred for follow-up of an osteochondral lesion. Incidental finding of an accessory soleus. Axial FSE T1 at different levels from (a) proximal to (b) distal demonstrates the muscle belly anterior to the soleus, superficial to the flexor retinaculum (black arrows). The tendon descends to insert in the medial aspect of the calcaneus. c Sagittal plane CT reconstruction with soft tissue algorithm in the same patient also allows visualisation of the muscle, extending to insert in the calcaneus (black arrowhead)Back to article page
