Ultrasound of the calcaneal tendons –
Left:
Mild localized swelling with partial fibre disruption and decreased echogenicity is noted for the gastrocnemius over a distance of 15 mm proximal to the calcaneal tubercle. A superficial linear mineralization of 7mm length is seen 5 mm proximal to the calcaneal tubercle. Marked localized swelling with partial fibre disruption and decreased echogenicity is noted for the common calcaneal tendon over a distance of 20 mm and immediately proximal to the calcaneal tubercle. The affected measures approximately 15 mm in width. Multiple, small, mineralized bodies are seen.
The bone surface of the calcaneal tubercle presents marked irregularity and modeling with concave defects and multiple protruding new bone formations. The calcaneal bursa reveals mild enlargement and wall thickening.
