When to Use
Radiologic classification and prognostic assessment of Traumatic Brain Injury (TBI).
Superior prediction of 6-month mortality compared to Marshall and Rotterdam scores.
Identifying which "mass lesions" are highest priority for evacuation.

Pearls/Pitfalls
Massive IVH weighting
The Helsinki score is unique for its heavy weighting of IVH (+3 points). This reflects modern data showing that IVH in a trauma context is an exceptionally poor prognostic marker, often signifying severe shear injury or massive secondary pressure spikes.
