A 20-year-old man is brought to the emergency department from
the site of a motorcycle accident. He is unconscious and has a broken
femur, humerus, and extensive facial injuries. Axial CT shows
a white layer on the lateral aspect of the left hemisphere that is approximately
5 mm thick and extends for 12 cm. This observation
most likely represents:

(A) Epidural hemorrhage/hematoma

(B) Parenchymatous hemorrhage in the cortex

© Subarachnoid hemorrhage

(D) Subdural hemorrhage/hematoma

(E) Ventricular hemorrhage

Good job bergkamp

Answer D: Trauma may cause epidural hemorrhage, subdural hemorrhage, or subarachnoid hemorrhage. Acute subdural hemorrhage/hematoma will appear white in CT and will usually present as a comparatively thin but long defect.

Epidural hemorrhage will usually be seen as a shorter but thicker lesion and may appear
loculated (have some sort of internal structure).

The structure (shape) of this lesion does not conform to hemorrhage into the substance of the brain (brain parenchyma), into the subarachnoid space (or cisterns), and certainly not to hemorrhage into the ventricles.

Have to go and will answer the rest later TY all.
