Ultrasonography has been increasingly used the last years for the identification of calcium pyrophosphate dihydrate crystal deposition (CPPD) in joints and has demonstrated to be a reliable and feasible tool in most of the studies published. However, it is common experience between sonographers that in daily clinical practice CPP identification by US is rather challenging as crystal deposits are not always numerous and diffuse. Furthermore, other conditions can mimic CPP deposition leading to a wrong diagnosis. During this section will be exposed the main US features of CPP deposition as well as the principal pitfals that could mislead diagnosis. Some tips and tricks that could help sonographers to identify correctly CPP deposition will also be explained.
