LEFT FRONTAL HEMORRHAGIC CONTUSION.

LEFT FRONTAL HEMORRHAGIC CONTUSION. RIGHT TRAUMATIC SUBARACHNOID HEMORRHAGE

The single arrow head points to an area of hemorrhagic frontal contusion. The arrow points to acute blood interdigitating within the sulci of the occipito-parietal region. This is traumatic subarachnoid hemorrhage. Nontraumatic subarachnoid hemorrhage should always be considered to be secondary to a ruptured aneurysm or hemorrhage from an A-V (arteriovenous) malformation and necessitates an angiogram for confirmation.
