Pseudo-subarachnoid Hemorrhage

Case A 19-year-old man was admitted in the intensive unit after a suicide attempt by hanging. He had been found in cardiac arrest of imprecise duration. Cardiac massage was performed for 40 minutes during transfer. The patient was in a deep coma with Glasgow score at 3/15. Unenhanced Brain Computed Tomography (CT) performed after five hours (Figures 1a, b, c and 2a) demonstrated bilateral hypodensity of the basal ganglia (white arrowheads). Hyperdensity of the cerebral arteries seemed to be related to the underlying brain hypodensity, with decrease in gray-white differentiation due to edema. Unenhanced CT after 30 hours (Figures 1e, f, g and 2b) showed progression of brain edema with collapse of the sylvian fissures, basal cisterns and cortical sulci (black arrows). Diffuse
