Abstract

With the advent of computed tomography (CT), the intracranial arachnoid cyst of which the diagnosis had been unlikely to be made before is detected without difficulty now. Reports of intracranial arachnoid cysts have increased in number. It appears on CT scans as a sharply circumscribed hypodense lesion of CSF density, most frequently located in the middle cranial fossa. It has no direct communication with the subarachnoid or ventricular systems. Recently we have experienced two cases of intracranial arachnoid cyst of the middle cranial fossa. Pathogenesis, diagnosis and treatment of the intracranial arachnoid cyst will be reviewed.
