There is extensive infra and supratentorial subarachnoid haemorrhage demonstrated centred at the suprasellar cistern and extending into the premedullary cistern, cerebellopontine cistern, into bilateral Sylvian fissures, along the floor of the middle cranial fossa and falx cerebri anteriorly.
There is also widespread sulci haemorrhage seen in bilateral frontal, anterior temporal and parietal as well as right anterior occipital lobe.
An area of ill-defined hypodensity is shown in the right frontal lobe appears suspicious for an area of established infarction.
No intraventricular blood. No midline shift. No focal mass identified.
CT angiogram (not shown) demonstrate peripheral right MCA dilatation, suspicious for an aneurysm.
