Which CT finding may be associated with a better prognosis?

• A. Small contusions may be associated with a better prognosis.
• B. Large contusions are a better sign.
• C. Diffuse axonal injury is a good sign.
• D. Midline shift is a good sign.

Answer: (A)

In traumatic brain injury imaging, prognosis follows the extent and distribution of injuries seen on CT. Small contusions reflect limited focal tissue damage with little or no mass effect, so they often correspond to a relatively better outcome, especially when there are no additional injuries or swelling. In contrast, large contusions indicate more extensive cortical damage and a higher likelihood of edema, hematoma expansion, and neurological deficits, which worsen prognosis. Diffuse axonal injury involves widespread disruption of white matter tracts and is typically linked to severe injury and poorer outcomes, even if the CT isn’t dramatic initially. Midline shift shows significant brain displacement due to mass effect or swelling, signaling elevated intracranial pressure and a worse prognosis. So, the CT finding most aligned with a better prognosis is small contusions.
