Achilles insertional calcific tendinosis

Case contributed by Dr Varun Babu

Presentation

Long standing posterior ankle pain with recent aggravation and localized tenderness.

Patient Data

Age: 35 years old
Gender: Male
MRI

MRI ankle

Thickened achilles tendon at it's insertion with intrasubstance PD hyperintense signals within the medial aspect. 

Two small intratendinous calcific foci - enthesophytes due to chronic repetitive stress identified in the altered signal fibres of the tendoachilles. 

Case Discussion

Repetitive microtrauma results in haemorrhage, intratendinous collagen degeneration and fibrosis , eventually culminating in calcific foci within the injured segment as a compensatory mechanism to counter the excess stress encountered.
