Figure 4:

New onset hydrocephalus in patient 19, a 58-year-old M who presented after unwitnessed non-shockable rhythm cardiac arrest due to drug overdose. Initial HCT (C, D) was performed 2 hours after CA and showed diffuse loss of grey-white matter differentiation and small ventricles. Portable MRI (A, B) was performed 47 hours after CA and shows ventriculomegaly and diffuse FLAIR signal abnormalities consistent with HIBI in the bilateral cortex, deep structures, and cerebellum.
