case_images: Sagittal and axial T2W FLAIR MRI head: high signal intensity consistent with acute subarachnoid blood in the prepontine cistern (a), right slyvian fissure (b), interpeduncular (c) and ambient (d) cisterns (arrows).

case_images: fig1-26334941211023542
case_images: The patient had an urgent magnetic resonance imaging (MRI) head scan which demonstrated an extensive SAH involving the prepontine cistern (Figure 1a), the right sylvian fissure (Figure 1b), interpeduncular (Figure 1c) and ambient (Figure 1d) cisterns.
case_images: Axial T2W (a) and DWI (b) MRI head: high signal intensity in the right frontoparietal cortex MCA territory consistent with acute ischaemia.

case_images: fig2-26334941211023542
case_images: There was a suspicious focal dilation in the bifurcation of the right middle cerebral artery (MCA), suggestive of an aneurysm causing the bleed and area of ischaemia (Figure 2).
case_images: Axial non-contrast CT head (a and b): high density in right slyvian fissure (arrrows) consistent with subrachnoid blood.

case_images: Here, she had computed tomographic (CT) (Figure 3) and magnetic resonance angiography (MRA) head scans (Figure 4) which confirmed an aneurysm of the right MCA.
case_images: Volume rendered image MR angiogram of the Circle of Willis: right M1 segment of MCA aneurysm (arrow).
