“…As seen in Table 1, the total number of false positive cases (13) was equivalent to 50% of the true positive cases (26) in this study. Signs of peroneal tenosynovitis include the appearance of fluid collection within the common peroneal tendon sheath and hypertrophy of the tendon on T2-weighted sagittal and axial images 11,12). However, hypertrophy of the tendon was difficult to determine during surgery and thus the positive predictive value of MRI for tenosynovitis was lower than that for other lesions.…”

“…Peroneal tenosynovitis was defined as the appearance of fluid collection within the common peroneal tendon sheath, increased signal intensity within the tendon, or hypertrophy of the tendon on T2-weighted sagittal and axial images11,12) and observation of increased synovial fluid and thickening of the tendon and synovial sheath during surgery. The low lying peroneal muscle belly was defined as extension of the muscle belly distal to the fibular groove (Fig.…”

BackgroundPatients with chronic lateral ankle instability also have peroneal tendinopathy often. However, preoperative MRIs of these patients are vague in many cases. Our study was performed to see the reliability of MRI findings of peroneal tendinopathy in patients with chronic lateral ankle instability.MethodsMRI images for 82 patients who had chronic lateral ankle instability, and had received surgical treatment between March 2006 and November 2009 were compared with impressions from operating rooms. The mean age of patients was 36.4 years (range, 15 to 64 years), 82 ankles were studied, and patients with rheumatoid diseases were excluded from the study.ResultsOf the 82 cases, 26 were true positives, 38 true negatives, 13 false positives and 5 false negatives. Of 39 cases of peroneal tendinopathy diagnosed from MRI, 14 had peroneal tendon partial tears, 15 tenosynovitis, 3 dislocations, 17 low-lying muscle bellies, and 6 peroneus quartus muscles. Of 31 cases of peroneal tendinopathy observed in surgery 11 had peroneal tendon partial tears, 4 tenosynovitis, 5 dislocations, 12 low-lying muscle belliess, and 1 peroneus quartus muscle. Sensitivity and specificity of peroneal tendinopathy were 83.9% and 74.5%, respectively. Positive predictive value was 66.7%. Negative predictive value was 88.4%. Accuracy rate was 78.0%.ConclusionsMRI is a useful diagnostic tool for detecting peroneal tendinopathy in patients with chronic lateral ankle instability. However, MRI is vague in many cases. Therefore, a thorough delicate physical examination and careful observation is needed.

“…The pathogenesis of peroneal tenosynovitis is thought to be secondary to increased stress around fixed pulleys such as the retromalleolar groove, peroneal tubercle, or undersurface of the cuboid bone. Other causes include ankle inversion injuries and lateral malleolar and calcaneal fractures (13). Acute peroneal tenosynovitis is typically seen in athletes who resume activity after a layoff.…”

Diseases of the peroneal tendons and superior peroneal retinaculum (SPR) are frequently underdiagnosed causes of lateral ankle pain and instability. Common diseases include tenosynovitis, rupture, and dislocation of the peroneal tendons as well as injuries to the SPR. Many anatomic variants, such as a flat or convex retromalleolar fibular groove, hypertrophy of the peroneal tubercle, an accessory peroneus quartus muscle, a low-lying peroneus brevis muscle belly, or an os peroneum, may be associated with or predispose to lateral ankle disease. Magnetic resonance (MR) imaging is excellent for detecting soft-tissue and bone variants and abnormalities related to the lateral ankle. Knowledge of the MR imaging appearances of these entities aids radiologists in making the precise diagnosis of disorders of the peroneal tendons and SPR. Pitfalls and normal variants of the peroneal tendons, including magic angle phenomenon, pseudosubluxation of the peroneus brevis tendon, a bifurcated or mildly crescentic peroneus brevis tendon, insertion of the peroneus quartus tendon into the peroneus brevis tendon, and the presence of an os peroneum are important to recognize. It is also useful to be familiar with the MR imaging appearances of SPR injuries, which can be an overlooked but treatable cause of lateral ankle pain and instability.

“…Tenosynovitis is common in the athletic population, 24,26 being notably associated with acute inversion injuries and overuse with chronic lateral ankle instability. 27,28 As mentioned earlier, a thin layer of effusion within the tendon sheath can be normal, 29 whereas circumferential involvement with hypoechoic fluid or hypoechoic synovial tissue is more typical of tenosynovitis ( Fig. 1).…”

Sports and overuse injuries of the ankle and foot are commonly encountered in clinical practice. Ultrasound (US) has been established as an excellent diagnostic modality for foot and ankle injuries, providing a rapid noninvasive, economical, and readily available tool that is well tolerated by the patient with acute or chronic pain. The opportunity for dynamic examination is another advantage of US in evaluating ankle and foot pathology, where maneuvers such as muscle contraction and stressing of the joint may be particularly helpful. In many cases, US can be used as a first-line and only imaging modality for diagnosis. This article focuses on ankle disorders related to sports or overuse that affect tendons, including tendinosis, tenosynovitis, paratendinitis, rupture, dislocation, and ligaments that are commonly torn. The sonographic features of certain common foot disorders related to physical activity and overuse are also discussed, including plantar fasciitis, Morton's neuroma, stress fractures, and plantar plate injury.
