====== 1881 ======

[[1880]]-[[1882]]

In [[1881]], Litten first described an intraretinal hemorrhage associated with [[subarachnoid hemorrhage]] in the German literature.

However, Terson's description of vitreous hemorrhage following [[subarachnoid hemorrhage]] in [[1900]] is now associated with this syndrome.

[[Brainstem tumor]]s were first described by Kummel in [[1881]]
((Kummel B. Beitrag Zur Kasuistik Der Gliom Des Pons Und Der Medulla Oblongata. Klin Medizin. (1881).))
and Monakow 
((Monakow C. Histoire naturelle des tumeurs cérébrales, en particulier du gliome. Encéphale. (1926):117–89.)).
The first nosological classification was reported in [[1926]] by Bailey and Cushing who emphasized, for the first time, that [[brainstem glioma]]s could develop from certain embryological cells 
((Bailey P, Cushing H. A classification of tumors of the glioma group on a hystogenesis basis. Philadelphia: Lippincot; (1926).)).
