Rotterdam CT Score (Traumatic Brain Injury)
Rotterdam CT score for traumatic brain injury (Maas 2005): basal cistern status, midline shift, epidural mass, and intraventricular/subarachnoid blood give a 1–6 score banding 6-month mortality.

Example
- Basal cisterns
- Absent (+2)
- Midline shift > 5 mm
- Yes
- Intraventricular blood or traumatic SAH
- Yes
Result: Rotterdam 6/6 — 6-month mortality ≈ 61%.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Mortality
- 6-month mortality by score: 1 → 5%, 2 → 7%, 3 → 16%, 4 → 26%, 5 → 53%, 6 → 61%. An additive head-CT scale that outperforms the older Marshall scheme; a prognostic estimate, not an order.
What you enter
- Basal cisterns
- Midline shift > 5 mm (+1)
- Epidural mass lesion present (subtracts 1)
- Intraventricular blood or traumatic SAH (+1)
How this is calculated
- Points
- Basal cisterns normal 0 / compressed 1 / absent 2; midline shift > 5 mm +1; epidural mass absent +1 (inverted); intraventricular blood or traumatic SAH +1; plus 1 by convention. Total 1–6.
