New concepts on the aetiology and vascularization of meningiomata; the mechanisms of migraine; the chemical processes of the cerebrospinal fluid; and the formation of collections of blood or fluid in the subdural space

Abstract

In this communication it is our intention to describe in detail the vascular anatomy of the dura mater, and particularly as its peculiarities throw light on the actiology and vascularization of the meningiomata, a class of tumours that has played a large part in the moulding of the techniques of neurosurgery. We believe that our work also helps in the elucidation of the puzzling phenomena of the circulation and chemistry of the cerebrospinal fluid. The relevant pathological activities of the subdural space and the mechanisms of migraine will also be discussed.
