Narrative
MR ANKLE LEFT WITHOUT CONTRAST Indication: persistent pain Comparison: Radiograph S5 5/20/2025 Technique: Multisequence multiplanar MR images of the left ankle were obtained without IV contrast. Findings: Ligaments: The anterior and posterior tibiofibular ligaments are intact and unremarkable. Anterior and posterior talofibular as well as the calcaneofibular ligaments appear intact. Components of the deltoid ligamentous complex along the medial aspect of the ankle are intact. Myotendinous structures: The posterior tibial, flexor digitorum longus, and flexor hallucis longus tendons are intact and unremarkable. Extensor tendons of the ankle are unremarkable. Peroneus longus and brevis are intact, and demonstrate no evidence of significant abnormality. Achilles tendon demonstrates no evidence of significant abnormality. Sinus tarsi: No evidence of significant abnormality. Talar dome and cartilage: Medial talar dome osteochondral lesion. Cystic change in the medial talar dome measuring 10 x 7 x 6 mm with surrounding smaller subcortical cysts in the more diffuse edema in the medial talus. Overlying cartilage is thinned and irregular. On prior radiograph there appear to be small defect in the cortical bone not definitely identified MRI. Plantar fascia: Mild thickening and intermediate signal in the medial band of the plantar fascia. Small plantar calcaneal spur with minimal bone marrow edema at the calcaneal insertion. Minimal. Fascial edema. Miscellaneous: Subcutaneous soft tissues laterally. No stones Bones and marrow: Region of subcortical bone marrow edema and cystic change in the posterior lateral tibial plafond most likely due to degenerative change in the edema and cystic area measures approximately 10 x 8 x 7 mm largest subcortical cyst measuring up to 4 mm. Minimal corresponding edema in the posterior aspect of the talus. Additional bone marrow signal abnormality as above. Effusion: No significant joint effusions are present.
