Reason: eval for lateral foot pain (? Peroneal tendon injury) History: pain in the area of os peroneum / calcaneocuboid joint The flexor and extensor tendons appear intact. There is increased signal abnormality within the distal right radius brevis tendon at the level of its insertion on the tuberosity of the fifth metatarsal indicating moderate tendinopathy (image 23; series 701). There is subcutaneous soft tissue edema in the surrounding area. Peroneal tendons appear intact. The Achilles tendon is normal in appearance. There is a lobulated focus of fluid signal intensity along the medial aspect of the flexor digitorum longus at the level of the medial malleolus which may represent ganglion formation. The lateral collateral ligament complex appears intact the distal tibiofibular syndesmotic complex appears intact. The components of the deltoid ligament appear intact. There is subcutaneous edema along the dorsal aspect of the foot which is nonspecific. There is a small amount of fluid within the retrocalcaneal bursa which may reflect a mild bursitis. There is minimal increased signal abnormality within the posterior aspect of the calcaneus at the level of the insertion of the Achilles tendon which may reflect tiny cyst formation.
Findings indicating tendinosis of the peroneus brevis tendon with subcutaneous and soft tissue edema in the surrounding area which may be reactive in etiology. There is also nonspecific subcutaneous edema along the dorsal aspect of the foot. Other findings as described above.
