FIG 3. Patient 7. Follow-up DWI show superimposed infection of a right RSE in this 10-year-old boy with right temporal and parafalcine SDEs.
A, Coronal contrast-enhanced T1WI (800/20) with MT shows capsular enhancement (arrows) of the right parietal subdural collection and the anterior aspect of the right temporal base SDE.
B, Axial DWI (4000/110, b = 1000 s/mm2) shows increased diffusion in the collections.
C, Follow-up coronal contrast-enhanced T1WI (800/20) with MT shows no substantial change in the capsular contrast enhancement of the collection.
D, Follow-up axial DWI (4000/110, b = 1000 s/mm2) shows increased signal intensity in the collection (arrows) and the interhemispheric fissure, suggesting superimposed infection.
