NCCT confirmed left cortical SAH (see Figure  1), most pronounced in the left frontal and temporal lobe sulci, while CTA showed hypervascularity on the left, but was negative for aneurysm or vascular malformations.
This axial T2-weighted MRI shows widespread bilateral sulcal FLAIR hyperintensity, which is consistent with SAH.

MR perfusion exhibited mild hyperperfusion in the left MCA territory, while the right MCA territory showed hypoperfusion, consistent with the near occlusion of the right ICA (Figure  2).
