History of chronic subdural hematoma

The first description of a chronic subdural hematoma was made in 1658 by JJ Wepfer, followed in 1761 by Morgagni. A possible case was described by Hon or de Balzac in 1840 including its traumatic origin and surgical treatment. Virchow, in 1857, denied a traumatic origin, and gave the name of "pachyme ningitis hemorragica interna" to this pathology which he explained by infla mmatory processes. The traumatic etiology of chronic subdural hematoma was recognized in the XXth century, especially, by Trotter in 1914. Pathophysio logy was considered later on in the XXth century.
