[Post-traumatic tarsal tunnel syndrome: interest of muscular MRI].

INTRODUCTION: Tarsal tunnel syndrome is a compressive neuropathy of the tibial nerve with multiple causes. This syndrome is difficult to diagnose and can be missed because of its subjective symptomatology.

OBSERVATION: In our patient, suspected post-traumatic tarsal tunnel syndrome was confirmed at MRI. This case highlights muscle signal anomalies caused by their denervation in the tibial nerve territory.

CONCLUSION: MRI can provide supplementary information to the electromyography (EMG) and contribute to positive and etiologic diagnosis of peripheral nerve lesions.
