Rotterdam CT score of traumatic brain injury

Last revised by Dr Jeremy Jones on 23 May 2017

The Rotterdam CT score of traumatic brain injury is a relatively recently described classification aimed at improving prognostic evaluation of patients admitted with acute traumatic brain injuries

It was published in 2006 1 and is gaining in popularity. Along with the Marshall classification system, at the time of writing (June 2016), it is the most commonly used system to classify CT brain in traumatic brain injury. 

It should not be confused with the Rotterdam criteria for polycystic ovarian syndrome

The Rotterdam classification includes four independently scored elements. Like the Marshall system, it includes 1) degree of basal cistern compression and 2) degree of midline shift. It does not, however, include contusions, but rather restricts mass lesions to 3) epidural hematomas, and adds 4) intraventricular and/or subarachnoid blood 1

Each of these is given a score, and these scores are tallied, with the addition of 1 to the total. In other words, a completely normal appearing scan has a Rotterdam score of 1 and the worse possible score is 6, which makes it comparable to the Marshall system 1

  • basal cisterns
    • 0: normal
    • 1: compressed
    • 2: absent
  • midline shift
    • 0: no shift or <= 5 mm
    • 1: shift > 5 mm
  • epidural mass lesion
    • 0: present
    • 1: absent
  • intraventricular blood or traumatic SAH
    • 0: absent
    • 1: present

In adults the mortality at six months increases with the score 1

  • score 1: 0%
  • score 2: 7%
  • score 3: 16%
  • score 4: 26%
  • score 5: 53%
  • score 6: 61%

Children have lower mortality in lower Rotterdam scores (scores 2 and 3), and higher mortality at higher scores (scores 4 to 6) 2
