The first description of a chronic subdural hematoma was made in 1658 by J.J. Wepfer, followed in 1761 by Morgagni. A possible case was described by Honoré de Balzac in 1840 including its traumatic origin and surgical treatment.
Virchow, in 1857, denied a traumatic origin, and gave the name of “pachymeningitis hemorrhagica interna” to this pathology which he explained by inflammatory processes.
The traumatic etiology of chronic subdural hematoma was recognized in the XXth century, especially by Trotter in 1914. Pathophysiology was considered later on in the XXth century.
