Splitting of of peroneus brevis tendon is more common than full thickness tear including that of the tears of the long peronius tendon. Axial proton desity fat sat MRI shows splitting (has an inverted 'u' shape) in the peronius brevis and an intact peronial longus. There is fluid along the tendon sheath. The sagittal images are misleading.
