54-year-old male with bilateral knee pain. MENISCI:Left Knee: Linear increased signal is noted in the posterior horn of the left medial meniscus, extending to the articular surface. Findings are compatible with a radial tear but there is also a vertical component (series 601, image 21). The anterior horn of the left medial meniscus and both horns of the left lateral meniscus are unremarkable.Right Knee: Subtle increased signal in the posterior horn of the right medial meniscus, suggestive of a partial undersurface tear. The anterior horn of the right medial meniscus is unremarkable. Myxoid degeneration is noted in the anterior horn of the right lateral meniscus, which is otherwise unremarkable.ARTICULAR CARTILAGE AND BONE: Left Knee: No significant abnormality noted.Right Knee: Lobulated, T2-hyperintense lesion in the distal femoral metaphysis is compatible with a benign enchondroma. No significant bone marrow edema. Normal tricompartmental articular cartilage.LIGAMENTS: No significant abnormality noted in either knee. EXTENSOR MECHANISM: No significant abnormality noted in either knee.ADDITIONAL
