What is the MRI appearance of Achilles tendon rupture?
Achilles tendon ruptures are commonly seen following sports-related injuries and most frequently seen in men between the ages of 30 and 50. Patients usually report a “pop” during forceful dorsiflexion. On MRI, sagittal images are the most helpful to make this diagnosis. The tendon tear usually occurs in the hypovascular watershed region located 2 to 6 cm proximal to the calcaneal insertion ( Figure 57-2 ). In addition to discontinuity of tendon fibers, a large amount of surrounding edema is typically present in the acute setting. Any gap between the proximal and distal ends of the tendon should be noted because this will impact surgical management.
