ABSTRACT : Our objective is to describe the characteristic MR imaging features of longitudinal tears of the peroneus brevis tendon and to describe pathologic conditions and normal variants that are associated with these tears which may require surgical intervention at the time of primary tendon repair. 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. Peroneal tendon subluxation typically occurs in athletes with a sudden forceful dorsiflexion and inversion of the ankle. Evaluating the tendons on serial images allows discrimination between tendon subluxation, dislocation, or tear. . 2 Oden RR. 3, Seminars in Ultrasound, CT and MRI, Vol. Patients typically present with pain and swelling along the posterior aspect of the lateral malleolus.1 They may have felt a distinct pop at the time of acute injury or may report recurrent popping or snapping with activity, particularly when ascending or descending stairs. 2, No. Roentgenol., Jan 1997; 168: 135 140. 3, The Journal of Bone & Joint Surgery, Vol. The shape of the 89, No. Warmth in the affected area. 1, Operative Techniques in Sports Medicine, Vol. The peroneus longus tendon (red arrow) is seen between the split portions of the peroneus brevis tendon. 12 Rosenberg ZS, Bencardino J, Astion D, Schweitzer ME, Rokito A, and Sheskier S.
