Summary
Subtle MRI findings can reveal peroneal tendon tears, often presenting as longitudinal splits. Axial views are key to differentiating these tears from peroneal tendonitis in lateral ankle pain.
Area of Science:
- Radiology
- Orthopedic Imaging
- Musculoskeletal MRI
Background:
- Peroneal tendon injuries are a common cause of lateral ankle pain.
- Accurate diagnosis is crucial for effective treatment and surgical planning.
Observation:
- This study reviewed MRI scans of four patients with chronic lateral ankle symptoms.
- MR imaging (1.5 T) was performed prior to surgical exploration of the peroneal tunnel.
Findings:
- Longitudinal tendon splits, characterized by a "multipartite" appearance on axial images and "flame-shaped" distal views, indicate peroneal tendon tears.
- Surgery confirmed peroneus brevis and longus tendon lesions in all patients.
- Insufficient superior peroneal retinacula were noted in patients with peroneus brevis tendon splits.
Implications:
- Axial MRI sequences are valuable for distinguishing peroneal tendon splits from tendonitis.
- Understanding these subtle MRI findings improves diagnostic accuracy for peroneal tendon pathology.
- This knowledge aids in surgical decision-making for lateral ankle pain.
