Reason: Assess for R achilles degeneration/tear/cystic changes History: Swollen, painful lump 4-5cm proximal to achilles insertion on calcaneus; pain with walking TENDONS: There is thickening and intermediate signal intensity within the Achilles tendon indicating moderate to severe tendinosis. There is linear fluid signal intensity within the medial fibers of the Achilles tendon approximately 4 cm proximal to its insertion on the calcaneus indicating partial thickness tearing. There is no significant retraction. The flexor and extensor tendons appear intact. The peroneal tendons appear intact. There is circumferential fluid within the tendon sheath of the flexor hallucis longus just proximal to the master knot of Henry which may represent a tenosynovitis/intersection syndrome.LIGAMENTS: The lateral collateral ligament complex appears intact. The distal tibiofibular syndesmotic complex appears intact. The components of the deltoid ligament appear intactARTICULAR SURFACES AND BONE: There is increased bone marrow signal abnormality within the base of the second metatarsal which may reflect degenerative change. No additional bone marrow signal abnormality is identified. ADDITIONAL
Moderate to severe tendinosis of the Achilles tendon with partial thickness tearing as described. No significant retraction is identified. Other findings as above.
