Hématome extradural

As blood accumulates, it starts to compress intracranial structures, which may impinge on the third cranial nerve , [6] causing a fixed and dilated pupil on the side of the injury. Other symptoms include severe headache ; weakness of the extremities on the opposite side from the lesion due to compression of the crossed pyramid pathways ; and vision loss, also on the opposite side, due to compression of the posterior cerebral artery. In rare cases, small hematomas may be asymptomatic. The trigeminal nerve may be involved late in the process as the pons is compressed, but this is not an important presentation, because the person may already be dead by the time it occurs.
