The presence of a crescentic shadow in roentgenograms, caused by a calcified area in the wall of the cyst, has been observed in two or three instances. The finding of similar shadows in cases of suspected brain tumor, while not pathognomonic, should at least suggest the possibility of a dermoid cyst. The whole subject of intracranial dermoid and epidermoid cysts, cholesteatomas and teratomas has become considerably confused in nomenclature, as the nature of the lesion depends not only on the cell layers from which these growths arise—be they epithelial or endothelial in origin—but also on the location and the nature of the contents
