Normal limits of the lateral cerebral ventricles on the lateral phlebogram: a statistical analysis

The highest points of the subependymal veins of the lateral cerebral ventricles (frontal horn, body and atrium) and the height of the body have been evaluated in selected patients. Through a statistical analysis, they have been demonstrated to depend on the height of the supratentorial compartment of the skull. Taking into account this relation, the results obtained furnish reliable criteria for evaluating ventricular enlargement or sectional deformity.
