17-year-old female with history of lateral knee pain status post injury MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: The articular cartilage is within normal limits, with no significant thinning or clefts. Abnormal high T2 signal intensity of the lateral tibial plateau suggests bone marrow edema and possible bone contusion. However, there is no linear abnormal T1 signal intensity to suggest fracture.LIGAMENTS: The cruciate and collateral ligaments are intact. Small amount of abnormal high T2 signal intensity over the distal insertion of the lateral collateral ligament may represent edema from trauma.EXTENSOR MECHANISM: The extensor mechanism is intact, without significant joint effusion.ADDITIONAL
Lateral tibial plateau bone contusion, and other findings as above.
