Abstract

Believing that every one encounters difficulty in the interpretation of pneumographic roentgenograms outlining various portions of the ventricular system, we made a study of a group of cases of tumor of the brain. It is our opinion that a systematic and comparative analysis of any set of properly taken roentgenograms can reduce the error of interpretation almost to the vanishing point.

In this study of one hundred and twenty cases of tumor of the brain in which the diagnosis was verified, we have compared the roentgen films in each case with the normal ventricular outline and have made it possible visually to comprehend the situation on a printed form (fig. 1). This form as used as a routine is printed on the scale of one-half the original size. The upper row of diagrams represents the ventricles as we believe they appear when normal. Beneath this is a space in which
