FIG 2. Images of a patient who experienced near-drowning at age 21-months. The patient died 16 days after the event.

A, Coronal T2-weighted FLAIR image (6000/2000/150), obtained 7 days after the event (class B), shows supratentorial moderate cortical tumefaction and hyperintensity (compared with the cerebellar cortex). Watershed areas score, 4/4.

B, Coronal T2-weighted FLAIR image (6000/2000/150), obtained 7 days after the event (class B). Basal ganglia involvement can be seen with fuzzy margins and T2 hyperintensity (lentiform nuclei, caudate nuclei, and subthalamic nuclei hyperintensity). Basal ganglia score, 4/4; total MR imaging score, 8/8.

C, Coronal T2-weighted FLAIR image (6000/2000/150), obtained 14 days after the event (class C). The cortex is no longer swollen but is still diffusely hyperintense. Watershed areas score, 4/4. More prominent basal ganglia hyperintensity can be seen. Basal ganglia score, 4/4; total MR imaging score, 8/8.
