Do Not Hallow until You Are out of the Wood! Ultrasonographic Detection of CPP Crystal Deposits in Menisci: Facts and Pitfalls

<table>Superficial CPP deposits in the meniscus (curved arrows). Frame (a): the appearance of these deposits in the in vivo examination (arrowheads). Frame (b): ex vivo US transverse scan of the meniscus at the level of the arrow. The arrowheads highlight a hyperechogenic line on the surface of the meniscus, corresponding to the CPP deposits. Frame (c): microscopic analysis of a sample of the meniscus surface, confirming the presence of CPP crystals.</table>
