Post-traumatic complications of arachnoid cysts and temporal lobe agenesis

Abstract

Six patients with arachnoidal cysts of the middle cranial fossa who presented with raised intracranial pressure are described. All of them had a history of trauma though in two of them it was a remote incident. They all showed radiological changes of an expanded middle cranial fossa and temporal lobe agenesis. The relationship of trauma to these congenital lesions is discussed.
