Results
Twenty three patients were included in our study, 10 men and 13 women. Eleven patients presented with right-sided chronic ankle pain while the left ankle was affected in 12 cases.
Nine patients had a history of previous ankle distortion,
ranging between several months to years preceding clinical presentation.
In 4 patients the request form for imaging mentioned overuse.
One patient had planovalgus foot deformity.
The mean width of the TP in these symptomatic patients was 5.6 mm (range 3.6 - 8.6 mm). Isolated tenosynovitis of the peroneus longus ( Fig. 4 and Fig. 5 ) was seen in 9 cases (grade 1 n=6 and grade 2 n=3). Isolated tenosynovitis of the peroneus brevis ( Fig. 6 ) was present in only 3 patients (grade 1 n=2 and grade 2 n=1).
Concomitant involvement of both peroneal tendons ( Fig. 7 and Fig. 8) was seen in 10 patients. (Table 3). Bone marrow edema is best detected on the FS T2-WI images and was present in 53 % (9 out of 17 patients)
