Diseases of the nervous system : a text-book of neurology and psychiatry . Gehirns, 2nd ed. * Brain, 1912.* Handbuch der Neurologie, Lewandowsky, vol. iii, 1912. 6 See Report of Clinic of Prof. M. Allen Starr, 1900-1909. 494 TUMORS OF THE BRAIN general tendency is toward diffuseness and principally in intracerebralgrowths degeneration with hemorrhage and fatty and cystic formationstakes place. Thus the symptoms are apt to develop slowly and inter-mittently in cortex or basal ganglia, occasionally from the may invade an entire hemisphere. Sarcomata are less frequent, restricing the term sarcoma morestrictly than is usual, and rejecting the compromise all gliomata show elements indistinguishable from usually develop slowly in the brain. Chloromata are leukemic in origin and are rare. They involve theperiosteum or the base and thus cause compression phenomena whichoften persist for some time. Fihroviata (neurofibromata) are comparatively common braintumors (10 per cent, in Tooths collection, including fibroglioma).. Fig. 240.—Infiltrating glioma of basal ganglia. They develop chiefly about the cerebellopontine angle (acoustic) butmay develop along other cranial nerves. Occasionally, they aremultiple. They develop slowly. Endotheliomata are comparatively frequent (14 per cent, in Toothscollection). They seem to confine themselves chiefly to the anteriorfossae. They are usually small and multiple, develop slowly andchiefly in the falx region. Chordomata are infrequent, and only rarely reach a considerable size.^ Carcinomata ( per cent.—Tooth), closely related to the endothelio-mata are usually secondary (metastatic), rarely primary. Psammomata, chordomata, lipomata, enchondromata, angiomata,osteomata, adenomata, cholesteomata, teratomata (pineal) ,2 anddermoids are among the rarities.
