    In geological terms, a geode is a nodule found mostly in limestone after solution of the mineral, with deposition of a beautiful array of crystals in the cavity. The term should not be applied to osteoarthrotic cysts, despite the popularization of its use, mostly by radiologists, during the last two decades or so. The geological process emphasizes the deposition, not the formation of the cavity, even though part of the cavity may persist after deposition. In contrast, with cysts, the emphasis is on the progressive lysis and not on what fills or lines the cavity. The lining usually is mostly fibrous or chronic inflammatory tissue.
