Fig. 2

a Dual-energy CT image of the meniscus reconstructed as a three-dimensional model (top view and front view), in which CPPD crystals (arrows) are colored in green. b CPPD crystals (arrow) are grossly observed in the meniscus. c Pathological analysis of a sample of the meniscus, confirming the presence of CPPD crystals at the site indicated by dual-energy CT. Rhomboid-shaped and rectangular-shaped CPPD crystals (arrow) with a weakly positive birefringence pattern are observed. d A Radiograph of the knee joint with liner calcifications (arrows) in the medial and lateral meniscus
