Images of an Achilles tendon with tendinopathy using CE and histological correlation. a Conventional US image of the insertion of the Achilles tendon in the longitudinal plane. The asterisks indicate the hypoechoic area without tendon thickening. CAL: calcaneus. b Image of USE at the same level as a. The red area of ​​the elastogram represented by asterisks is indicative of anomalous decrease of stiffness where biopsy was subsequently performed. c Histological image obtained with azan staining showing loss of the parallel fibrillar structure of the collagen, loss of fibre integrity (asterisks), adipose infiltration (circles), capillary proliferation (plus) and mucoid deposition (star).
