    Iodoventriculogram, lateral projection. Air in the lateral ventricles was left from a previous ventriculography, which revealed a moderate enlargement of the ventricles and a backward bowing of the aqueduct and the rostral half of the fourth ventricle suggesting a pontine lesion. The point of obstruction in the middle of the fourth ventricle is outlined clearly by Pantopaque. (See Fig. 3.)
