CT showing a subdural
hematoma in the anterior
portion of the skull and soft
tissue swelling on the left
posterolateral surface.
T1 weighted MRI showing an older subdural
hematoma on the left and a newer one on
the right. Over time, the composition of blood
more closely resembles water, making it
darker with time on T1 and brighter with time
on T2 MRIs.

4. Major Subdural Hematomas
Can you identify the
margins of the
hematoma?
What type of
herniation do you see
here?

5. Major Subdural Hematomas
The short arrows show
the margins of the
bleed. The significant
midline shift is causing
trapping of the
ventricles with CSF
seepage (long arrow).
Subfalcine herniation. Uncal herniation.

6. Epidural Hematomas
Appreciate the characteristic biconvex
nature of epidural hematomas.
