Acute traumatic brain injury is a worldwide public health crisis. Post-traumatic subarachnoid hemorrhage (SAH) is a finding that is present at a frequency of 40% according to data from American TCDB (1,2). Among the mechanisms that have been implicated as causes of post-traumatic SAH is the cortical bleeding through the subarachnoid space. It is estimated that the incidence of post-traumatic SAH is 11% to 60% in patients with traumatic brain injury. The brain CT is considered a technique with good sensitivity, economical and available in many hospitals worldwide. We have reviewed the literature and found some imaging characteristics of post-traumatic subarachnoid hemorrhage. We have called “the five preferences for post-traumatic SAH”.
