Bifrontal craniectomy performed in the interval since the previous scan.
Bifrontal scalp high density which may represent surgical material or haematoma.
Right frontal EVD tip abuts the right foramen of Monro.
The extensive right frontal and anterior temporal contusions are unchanged in size with slightly more surrounding hypodensity on today's study.
Degree of midline shift to the left is approximately 10 mm (previously 8mm).
Left cerebellar hemisphere contusion unchanged.
Surface CSF spaces are moderately more effaced than on the previous study.
Ventricular size is unchanged, with the right ventricle being more effaced than the left.
The basal cisterns the patent.
Conclusion:
Overally, marginal increase in midline shift and diffuse sulcal effacement since the previous study. No new hemorrhage or infarction.
