Comment:
The patient has a history of ankle and joint pain. Partial comparison is made with MRI of the left foot from Feb 17, 2007. Please note that the prior MRI of 2/17/07 was dedicated to the mid and forefoot, rather than the ankle.
And MRI examination of the left ankle was performed on a 1.5 Tesla magnet utilizing sagittal T1-weighte, sagittal STIR, and short axis and oblique coronal double echo spin echo images
There is an Osteochondral defect of the postero-medial talar dome, with a probable in situ osseous fragment best identified on image 16 of series 7 and image 13 of series 5, with subjacent marrow edema which measures approximately 8x11 mm.
There is mild focal tendinopathy of the peroneous longus tendon as it passes under the lateral malleolus with some mild adjacent subcutaneous edema.
Mild degenerative changes are present of the talonavicular joint. Bone islands are present in the cuboid and talus.
The Achilles tendon is normal. There is no fluid within the retrocalcaneal bursa.
Anteriorly, the anterior tibialis, extensor hallucis longus, and extensor digitorum longus tendons are normal.
Medially, the posterior tibialis, flexor digitorum longus, and flexor hallucis longus tendons are normal.
Laterally, the peroneus brevis tendons is normal, without subluxation, dislocation, tendinosis or tear.
The lateral collateral ligament complex is normal.
There is physiologic joint fluid without intrarticular bodies noted.
The subtalar joint is normal.
The plantar aponeurosis is normal.
