The dura mater of the convexity was opened after osteoplastic craniotomy. One looks into the arachnoid cyst onto the basal cisterns An opening has been made between the optic nerve and internal carotid artery (before the opening was made). In the subarachnoid space the blood vessels are visible (magnified). The cysts contents can now drain and a further increase of size is prevented. Upon successful operation pulsating cerebrospinal fluid can be seen.Across the top of the screen we see the middle wing of the sphenoid and the sphenoid sinus.
