Female 25 years old; Reason: eval for ATFL tear; talar injury History: ankle sprain Oct, 2014 still pain with walking laterally and still in aircast with limp and weakness TENDONS: A small amount of fluid is noted in the flexor tendon sheaths, likely of no clinical significance. The peroneal tendons are intact. The extensor tendons are intact. Achilles tendon is normal.LIGAMENTS: Fibers of the anterior talofibular ligament can be traced from the fibula to the talus on T2 axial images. However, on other sequences, the ATFL appears thickened and indistinct, compatible with prior sprain. The calcaneofibular ligament is thickened, compatible with prior sprain. Lack of fluid within the peroneal tendon sheaths argues against complete tear of the calcaneofibular ligament. The posterior talofibular ligament is intact. The distal fibular syndesmotic complex is intact. Loss of the normal striations of the deep deltoid ligament may represent prior injury.ARTICULAR SURFACES AND BONE: The bone marrow signal is normal. Other than a small bone island, the talus is normal. No osteochondral defects are seen.ADDITIONAL
Findings compatible with prior sprain of the anterior talofibular ligament and calcaneofibular ligament, without a fluid-filled tear of the ligaments seen. We see no injury to the talus.
