Presentation
Medial left foot swelling and pain.
Patient Data
The tibialis posterior tendon is diffusely thickened (as twice the right one), from the myotendinous junction till its insertion. Moderate synovial thickening and effusion, notably near its insertion. Yet, it shows intact fibers with no tears or degeneration.
Minimal rim of fluid is seen at the peroneal tendons insertion, reflecting element of mild tendinitis.
Normal sonographic features of tendo-Achilles with intact fibers and normal insertion site.
Unremarkable extensor tendons (anterior compartment).
No ankle joint effusion.
Case Discussion
Tibialis posterior tenosynovitis with synovial effusion is responsible, in this case, for medial foot swelling and pain. The left tibialis posterior tendon measures 8.7 mm compared to 4.7 mm on the right side. The diameter of more than 7 mm reflects tenosynovitis.
