Presentation
Confusion following fall and head injury
Patient Data
Bilateral crescentic low density peripherally at the cerebral convexity. These measure up to 1 cm in depth and represent subdural hemorrhage.
On the right, there are areas of increased density within - this represents acute hemorrhage.
Normal cerebral parenchyma.
Case Discussion
There are bilateral subdural hemorrhages in this patient with acute blood on the right.
Many will jump to the conclusion that this definitely represents acute-on-chronic subdural hemorrhage. That may be the cause, it is not definite unless there is evidence of the subdural collections being present prior to this study.
Traumatic subdural effusions may occur and can occur with accompanying acute hemorrhage.
