The first is to ascertain the presence of a neoplasm, and the second is to localize such a lesion accurately. Until both problems have been solved rational surgical measures cannot be carried out. To attain this goal every available diagnostic procedure capable of lending aid must be employed. Of considerable value in many instances is a roentgen examination of the head.

Two methods are available in every roentgenologic study of the intracranial cavity. The first is the ordinary examination of the head, employing various projections and exposures. According to the second method, roentgenograms are made after the introduction of air into the intracranial cavity—either encephalography or ventriculography, depending on the method of injecting the air. While these methods are extremely valuable
