Case history
Case history #1
A 14-year-old girl presents with a single generalized tonic-clonic seizure. She has no previous history of epilepsy. Neurologic exam, including assessment of parietal lobe function and visual fields, is completely normal. Computed tomographic scan is performed and reveals a lesion suggestive of an arteriovenous malformation.
Case history #2
A 27-year-old man develops a sudden onset of headache shortly after taking cocaine in a nightclub. He collapses with a right-sided hemiplegia, and his level of consciousness rapidly deteriorates. On arrival in the emergency department, he is in coma, extending to pain, with no eye opening and no verbal response. His left pupil is fixed and dilated.
