Brainstem folding in an influenza child with Dandy-Walker variant

Figure 3 Imaging of the basal ganglia after and before brainstem folding. A: After brain stem folding, swelling of the bilateral putamen, cauda nucleus, frontal lobe, parietal lobe, and occipital cortex, increased T2WI signals, and slightly enlarged bilateral lateral ventricle can be seen; B: Three days before brain stem folding, no swelling was observed in the bilateral putamen, caudate nucleus, frontal lobe, parietal lobe, or occipital cortex, with normal signals, and no expansion was observed in the bilateral lateral ventricles.
