About integrated imaging of complete peroneus brevis tendon rupture.
Peroneal tendons are frequently causes of lateral ankle pain and instability.
This is the case of a patient with an history of chronic ankle instability; gross irregularity of the retromalleolar groove and peroneal tubercle are evident.
Axial T2w (left) and Sagittal 3D Sharc Mri scans (0.3 tesla); red arrows indicate the gross irregularity of retromalleolar groove surface.
Sagittal multisequences and Axial mri scans of the same patient; red arrows indicate the complete rupture of the peroneus brevis tendon. (0.3 Tesla Mri).
The best way to understand the entire pathologic picture is to combine Mri and dynamic ultrasound imaging; on the video below you can appreciate the gross irregularity of the cortical surface that is the site of chronic tendon impingement. Repetitive microtraumas lead to complete tendon rupture.
