Hi, LemonTea. I think is B, the right answer
May I ask how do you know that you got it right when you did the NBME?I got that question right when I did the NBME
I remember I answered D
Lucid interval --> Epidural hematoma --> Middle meningeal artery
As Sabio said this is a coutercoup injury and the biggest clue is the lucid interval.
I searched in the website. It should be an NBME question:"Acute subdural hematoma - Following an acute SDH, coma is present from the time of injury in approximately 50 percent of cases. However, approximately 12 to 38 percent of patients have a transient "lucid interval" after the acute injury that is followed by a progressive neurologic decline to coma [2,10]. Posterior fossa SDH, like most space-occupying lesions in this location, presents with symptoms of elevated intracranial pressure including headache, vomiting, anisocoria, dysphagia, cranial nerve palsies, nuchal rigidity, and ataxia."
So, i am with a sub-dural hematoma (i.e B. Laceration of cerebral bridging vein)
