However, examination of the posteromedial region showed fluid gap with a myotendinous retraction suspicious for an accessory soleus tear muscles with a complete tear of tendon with a myotendinous retraction (Fig. 1).
Magnetic resonance images (a) sagittal STIR, (b) axial STIR, (c) sagittal T1 FSE, (d) axial T1 FSE show a complete tear of the right accessory soleus tendon with surrounding edema (arrows), myotendinous retraction measuring 26 mm, fluid gap into the Achilles fat pad (Kager's triangle), and minimal joint effusion in the tibiotarsal joint and in the subtalar joint. Achilles tendon (*).
