Von Monakow,1on the basis of the material of Durand-Fardel, stated that 10 per cent of all cerebral hemorrhages occur in the pons. From his description, however, it is not certain that he considered as pontile hemorrhages only those which occurred without evidence of additional hemorrhage within the brain. The more recent statistics of Novák2showed an exclusively pontile location of 5 per cent of 938 cerebral hemorrhages verified by medicolegal autopsy. Luce,3Böhne4and Neubürger5stated that the tegmentum is relatively often the seat of massive hemorrhage. Several authors (Gowers6and Luce) have maintained that pontile hemorrhage, while often located close to the midline, usually does not cross the median raphe. Most descriptions of pontile hemorrhage have been those of syndromes caused by unilateral pontotegmental lesions. Oppenheim,7however, stated that bilateral involvement of the extremities and cranial nerves in cases of pontile
