Ankle – Achilles tendon injury

CASE HISTORY

• Achilles injury or rupture evaluate for length and extent. 

TECHNICAL FACTORS

• Long- and short-axis fat- and water-weighted images were performed

KEY IMAGES

CASE FINDINGS

• Tendinosis within an enlarged Achilles is associated with a massive rupture that is encased in either: a) The peripheral fibers of the Achilles as a thin rim. b) The paratenon. c) Fibrous tissue.
• The length of the tear is measured by MRI at 7cm and tapers proximally.
• The tear begins 2cm above the superior calcaneal protuberance.
• Incidentally noted is small ankle effusion and mild to moderate midfoot arthrosis with subcortical erosions and pseudocysts.
• Mild calcaneal periostitis and small inferior spur.

CASE CONCLUSION

• 7cm long tear of the Achilles encased in a hypointense rim whose differential diagnosis is given and with a small tubular structure within most likely representing a well-developed residual persistent or untorn plantaris. See series 401 image 19 as an ex
