Male 26 years old Reason: r/o torn meniscus History: swelling pain MENISCI: There is an obliquely orientated focus of increased signal intensity extending through the peripheral fibers of the posterior horn of the lateral meniscus to the femoral articular surface, indicating a tear that is continuous with the interface of the meniscus with the meniscofemoral ligament. Furthermore the popliteomeniscal fascicles appear distorted and torn. The body and anterior horn of the meniscus demonstrate normal signal intensity and morphology. The medial meniscus demonstrates normal signal intensity and morphology.ARTICULAR CARTILAGE AND BONE: There is edema within the posterior aspect of the lateral tibial plateau as well as the lateral femoral condyle above the anterior horn of the lateral meniscus. The articular cartilage is intact.LIGAMENTS: The anterior cruciate ligament is abnormally thickened and of increased signal intensity indicating at least a partial thickness tear. The slope of the distal fibers is maintained but the proximal fibers are distorted. The posterior cruciate ligament demonstrates normal signal intensity and morphology. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Findings consistent with at least a partial-thickness anterior cruciate ligament tear as well as a tear of the posterior horn of the lateral meniscus.
