In published pneumographic ventricular studies the temporal or inferior horn of the lateral cerebral ventricle has received scant attention, and there is a persisting misconception of its shape to be found in textbooks of anatomy. The supracornual cleft and the body of this horn frequently appear as separable shadows in pneumograms, as will be described, and undergo typical changes in pathologic states.
We are taking this opportunity also to describe a method of ventricular analysis which we have found helpful for use as a routine. In this analysis the ventricular subdivisions proposed by Torkildsen and Penfield1 are used. These subdivisions are made up of those portions of the lateral ventricle which appear as separable shadow outlines on an anteroposterior roentgenogram. This may be understood by reference to figure 1, in which the view with the brow up should be compared with the left lateral view (L. L. V.), or
