Female 15 years old Reason: evaluate for cruciate ligament tear History: right knee injury and pain MENISCI: The posterior and anterior horns of both the medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: There is a focal depression of the lateral femoral condyle near the junction of the weightbearing and nonweightbearing portions with underlying high T2 signal compatible with impaction. There is thinning of the articular cartilage at the area of impaction. Additionally, there is associated high T2 signal in the posterior lateral tibial plateau.LIGAMENTS: High T2 and low T1 signal is evident within the anterior cruciate ligament consistent with an ACL tear. The posterior cruciate ligament is intact. The lateral collateral and medial collateral ligament complexes are normal in signal and morphology.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.High T2 and low T1 signal within the anterior crucial ligament consistent with an ACL tear.2.Contusion and impaction of the lateral femoral condyle with associated high signal in the posterolateral tibial plateau.3.No evidence of meniscal injury.
