Two axial transverse slices in similar slice location
1A : T2-weighted (T2-W) view shows heterogeneous parenchymal damage (arrow) of the right side of the ponto-mesencephalic junction displaying with high signal intensity of its lower half which contrasts with low signal of its upper half. Partial volume on a schwannoma of the left Vth cranial nerve (dotted arrow).
1B : DW view confirms duality of the low/high signal intensities within the lesion (arrow) with high signal intensity of the lower half featuring cytotoxic edema.
