 of France and England.

From the preface we quote the following : 



In the course of preparation of a monograph dealing with a series 

 of meningeal fibro-endotheliomata, a careful review was necessitated of 

 the pathological as well as the clinical aspects of these interesting tumors. 

 They have their point of origin in certain definite regions, and a tentative 

 subdivision had been made of those arising from the spinal meninges, 

 those from the basilar meninges, and those from the superior envelopes 

 of the brain. 



It was apparent that the spinal and basilar lesions usually arose from 

 the meninges at the point of exit of a spinal or cerebral nerve root, and 

 it was anticipated that many of the tumors of the cerebellopontile angle 

 which involve the acoustic nerve would be included in the series, for the 

 majority of them had previously been diagnosed from their gross ap- 

 pearance, though admittedly with some reservation on histological grounds, 

 as endotheliomata. 



Hesitation was felt in regard to the inclusion in the series of some of 

 the spinal cord tumors, and these doubts became intensified when the 

 lateral recess tumors came to be assembled and closely inspected. 



A thorough rehearsal of the material at hand, comprising twenty-nine 

 histologically certified cases, together with a much larger number of prob- 

 able though unverified ones, which nevertheless were useful from the 

 standpoint of their clinical data, so clarified many obscure matters relating 

 to these peculiar and unmistakable tumors of the VHIth nerve that they 

 have been made the subject of this separate study, and a report upon the 

 60 endotheliomata proper must await its turn. Unquestionably the acoustic 

 tumors are most distinctive growths and such relationship as they have 

 to the meningeal tumors occurring in the lateral recess will be pointed 

 out in its proper place. 



Some important monographs on the subject have already been published, 

 of which Folke Henschen's Inaugural Dissertation, 1910, is the most note- 

 worthy, but in all of them the various tumors of the cerebellopontile angle 

 have been incorporated, whereas the acoustic neuromas will alone occupy 

 our attention to the exclusion of other tumors of the recess except in so 

 far as they are of interest from the standpoint of differential diagnosis.
