17-year-old male patient with history of injury eight days prior and the examination concerning for medial meniscus tear. Due to the patient's body habitus and HD coil could not be utilized. An alternative coil was used instead resulting in slightly suboptimal image quality.MENISCI: There is branching signal abnormality within the outer one half of the posterior horn of the medial meniscus that extends to both the femoral and tibial articular surface indicating a complex tear. The body of the medial meniscus appears slightly attenuated relative to the lateral meniscus which may reflect additional tearing. The anterior horn appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is edema within the posterior aspect of the medial tibial plateau that may represent a contusion associated with the aforementioned medial meniscal tear. There is also edema within the posterior aspect of the medial femoral condyle which may represent an additional contusion. No fluid-filled articular cartilage defects are identified.LIGAMENTS: The ACL and PCL are intact. The superficial band of the MCL is intact. There is bandlike low signal intensity seen within the medial gutter between the medial femoral condyle and superficial band of the MCL which is of uncertain etiology and could represent a torn meniscofemoral coronary ligament or displaced meniscal flap. The LCL appears intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Complex tear of the posterior horn of the medial meniscus as described above. Bandlike low signal intensity within the medial gutter could represent a displaced meniscal flap or sprain/tear of the meniscofemoral coronary ligament.2. Bone contusions of the medial tibial plateau and medial femoral condyle.
