Abstract
I read with great interest the article by Hilario et al.[1][1] The authors retrospectively analyzed the MR imaging data from the first 30 days after injury in 108 patients with severe head trauma and found that the presence of posterior and bilateral brain stem injuries were poor prognostic signs.
Highlights
We previously investigated the MR imaging findings of traumatic primary brain stem injury.[2]
Superficial dorsal brain stem injury was found to be an indicator of a good prognosis, whereas only deep dorsal brain stem injury was related to a poor prognosis
We discussed 2 mechanisms of brain stem injury: primary brain stem injury that occurs after a direct impact of the brain stem against the tentorial free edge, and brain stem injury associated with diffuse axonal injury
Summary
Traumatic Brain Stem Injury: Evaluation by MRI I read with great interest the article by Hilario et al.[1] The authors retrospectively analyzed the MR imaging data from the first 30 days after injury in 108 patients with severe head trauma and found that the presence of posterior and bilateral brain stem injuries were poor prognostic signs. They analyzed the location of the brain stem lesions, they did not analyze the volume or depth of the brain stem lesions.
