Marshall ct classificarion
Marshall classification
Diffuse injury I (no visible pathology) No visible intracranial pathology seen on CT scan
Diffuse injury II Cisterns are present with midline shift of 0-5 mm and/or lesions densities present; no high or mixed density lesion >25 cm3 may include bone fragments and foreign bodies
Diffuse injury III (swelling) Cisterns compressed or absent with midline shift of 0-5 mm; no high or mixed density lesion >25 cm3
Diffuse injury IV (shift) Midline shift >5 mm; no high or mixed density lesion >25 cm3
Evacuated mass lesion
Any lesion surgically evacuated
Non-evacuated mass lesion
High or mixed density lesion >25 cm3; not surgically evacuated
Rotterdam Score
Rotterdam CT score predictor value
basal cisterns score • normal O • compressed 1 • absent 2 •
midline shift • no shift or shift ≤ 5mm 0 • shift>5mm 1 •
Epidural Mass • present 0 • absent 1 •
Traumatic SAB or IVH absent 0 • present 1 •
sum score +1 max = 6 consistent with: motor GCS Marshall class.
