    Silicon-containing particles were identified by transmission electron microscopy (TEM) in thin sections of two synovial fluids, which also contained calcium pyrophosphate dihydrate (CPPD) crystals, aspirated during acute attacks of pseudogout. Such particles, which are interpreted as probably being artefacts from glassware, were electron dense and similar in appearance to some CPPD or hydroxyapatite crystals.
