Image Interpretation: The Achilles tendon is thickened and hypoechoic, with marked hyperemia, most notable along the mid-tendinous portion. The retrocalcaneal bursa is distended, without hyperemia, but sonopalpatory pain is appreciated here. At the distal Achilles insertion, several small, hyperechoic foci are noted with posterior acoustic shadowing, consistent with calcifications and bony changes. The constellation of these clinical and sonographic findings suggests both midportion and insertional achilles tendinosis with associated retrocalcaneal bursitis and evidence of a Haglund deformity.
Teaching Pearl: Initial management of insertional Achilles tendinopathy and Haglund-related symptoms is often conservative, especially when prior treatment has not been attempted. Heel lifts/wedges, footwear modification, and progressive strengthening are commonly used, with care to avoid painful dorsiflexion-compression loads early in rehabilitation.
Ultrasound can help identify possible relevant contributors such as insertional tendinosis, partial tearing of deep fibers, calcific enthesopathy, and retrocalcaneal bursitis. These features can help guide whether treatment should emphasize load modification, bursal-specific interventions such as injection, tendon rehabilitation, or surgical consultation.
