Areas of intracranial calcification are not uncommonly seen in roentgenograms of the skull, associated with conditions of both a physiologic and a pathologic nature. This is particularly true since the Bucky diaphragm has made it possible to demonstrate the minute details of the skull and any calcareous material of any magnitude within it. The question will consequently arise as to the nature of the associated lesion, particularly if the roentgenograms were taken with the hope of establishing the diagnosis of an obscure disease of the brain. It is our purpose in this study to note first the pathologic possibilities and then to discuss more in detail calcification within intracranial tumors, particularly the gliomas. This is of special importance to the surgeon, for a calcified tumor not only gives positive testimony as to its situation, but also encourages him to believe that it has benign tendencies.
