Mild left cerebral convexity sulcal effacement and subtle subcortical loss of grey-white differentiation. The ventricular pattern is normal. No midline shift.

Acute left MCA stroke.

Case Discussion

This case shows how subtle the loss of normal grey-white matter differentiation can be in early acute stroke. Without the dense MCA hitting you in the face, one might easily fly past the subtle parenchymal changes.
