CT Scan Where is the lesion CT Scan question?

A 22-year-old man falls while skateboarding and strikes the right side of his head against the concrete. On physical examination only a minor scalp abrasion is present at the site of the impact, with minimal bleeding that stops in a few minutes. He is initially alert following this accident, but then became unconscious 30 minutes later.

Default Ans.

I choose E. Middle meningeal artery, classic history for epidural hematoma in the clinical vignette, and the CT scan shows the biconvex disk shape of this type of hematoma.

Hi bebix.
In this CT slice, you see an EXTRADURAL HEMATOMA, in temporo-parietal region, the vessel more frequently involved is the middle meningeal artery.
