Intraparenchymal haemorrhage in the posterior left temporal lobe with surrounding subarachnoid blood and blood layering on the tentorium cerebelli.

Hypodense region surrounding the haemorrhage in keeping with oedema. Mild effacement of the left ambient cistern. No midline shift.

The left transverse sinus is hyperdense.

Grey-white matter differentiation is preserved with no evidence of acute ischaemia. Old left lacunar infarct.

• Associated subarachnoid blood.
