Reason: Evaluate for Posterior Tibial Tendon Dysfunction left History: 41-year-old female with pain and edema along lateral aspect left ankle and anterior ankle with decreasing medial long arch TENDONS: There is circumferential fluid within the tendon sheath of the flexor hallucis longus just proximal to the master knot of Henry suggestive of a mild tenosynovitis/intersection syndrome (image 17; series 501). The flexor and extensor tendons appear intact. The peroneal tendons appear intact. The Achilles tendon is normal in appearance.LIGAMENTS: The lateral collateral ligament complex appears intact. The distal tibiofibular syndesmotic complex appears intact. The visualized components of the deltoid ligament appear intact.ARTICULAR SURFACES AND BONE: No bone marrow signal abnormality is identified. No full-thickness articular cartilage defects are seen. ADDITIONAL
1. Findings suggesting a synovitis of the tibiotalar joint.2. Findings suggestive of a mild tenosynovitis of the flexor hallucis longus as described above. The posterior tibialis tendon appears normal.
