The following cases show the increase in size of the Pac-chionian fossae and the emissaries in a general increase ofintercranial pressure: Case 5.—G., male, fifty years old. Choked disc, right more than of a tumor in the left parietal lobe. The roentgenogram showed slight pressure erosion of the inner surfaceof the skull in the parietal region, right side more than left. The sectionrevealed the existence of a tumor in the left occipital lobe, although thePacchionian fossa1 were deeper on the right side. INTRACRANIAL DISEASES 235 In this case, the greater pressure erosion, as well as thegreater swelling of the papilla, did not coincide with the sideon which the tumor was Fig. 90.—A dextrosinistral picture of the head of Case 3, page 234. It shows extremeenlargement and an increase in the number of the diploic veins. ot0f^--
