So, i am with a sub-dural hematoma (i.e B. Laceration of cerebral bridging vein)
I searched in the website. It should be an NBME question:
look at the following link: http://www.sikhstudentassociation.co...E5/nbme5_1.pdf
I think the correct answer is B. Because
1) I did not find any lucid interval in the patient history.
2) The symptoms happens 18 hours after the fall.
3) CT suggests extra-axial
hemorrhage, indicating either epi- or sub-dural hemorrhage.
Any other comment on this question would be appreciated.
