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 tumors were first described by Kummel in 1881 1) and Monakow 2). The first nosological classification was reported in 1926 by Bailey and Cushing who emphasized, for the first time, that brainstem gliomas could develop from certain embryological cells 3).
