Marshall CT Classification — Traumatic Brain Injury

The Marshall CT Classification (Marshall et al., 1991) is a 6-category system for grading the severity of intracranial pathology on CT in patients with traumatic brain injury (TBI). It stratifies patients from Category I (no visible pathology) through Category VI (non-evacuated high-density lesion >25 mL) based on basal cistern status, midline shift, and the presence of mass lesions. The classification is predictive of mortality and poor neurological outcome and guides neurosurgical decision-making.

Parameters

Marshall CT Category (Select the Best-Fitting Category)

Category I — Diffuse Injury I: No visible intracranial pathology on CT scan+1Category II — Diffuse Injury II: Basal cisterns present, midline shift 0–5 mm, no high/mixed density lesion >25 mL; may have bone fragments or foreign bodies+2Category III — Diffuse Injury III (Swelling): Basal cisterns compressed or absent, midline shift 0–5 mm, no high/mixed density lesion >25 mL+3Category IV — Diffuse Injury IV (Shift): Midline shift >5 mm, no high/mixed density lesion >25 mL+4Category V — Evacuated Mass Lesion: Any surgically evacuated mass lesion+5Category VI — Non-evacuated Mass Lesion: High/mixed density lesion >25 mL not surgically evacuated+6
