What should one do to make this lesion easier to see?
Use wider (subdural) windows which allow for easy distinction of acute blood from the adjacent skull.
The left frontal subdural haematoma measures 10 mm in depth and mildly effaces the subjacent left frontal lobe sulci. Small volume adjacent subarachnoid blood. There is 4 mm of midline shift towards the right at the level of the septum pellucidum. Subdural haematoma also noted at the posterior falx cerebri and extending onto the left tentorium cerebelli, measuring 3 mm.
A small hyperdense focus in the left occipital lobe is compatible with a small haemorrhagic contusion. No hydrocephalus. No intracranial mass. No skull fractures are noted, although a bone algorithm reconstruction has not been performed on this study.
