Seizures after intracerebral and subarachnoid hemorrhage. An 82-year-old woman presented with sudden-onset headache, dysphasia, and right hemiparesis while receiving anticoagulation therapy for chronic atrial fibrillation. Computed tomographic (CT) scan at admission (A) demonstrates an acute left temporal lobe intraparenchymal hematoma, with adjacent subdural and subarachnoid hemorrhage. The responsible lesion, an aneurysm of the middle cerebral artery, was treated surgically. During the postoperative period, she had episodes of right-sided facial twitching associated with transient worsening of her aphasia. A postoperative CT scan 3 months later (B) showed a hypodense lesion of the midtemporal lobe in the middle cranial fossa. Electroencephalographic (EEG) findings (C) demonstrated focal spike waves, consistent with seizure activity, followed by focal slowing and periodic lateralizing epileptiform discharge in the left hemisphere.

Mass lesion causing focal seizures. A 43-year-old woman presented to the emergency department after focal-onset right-sided clonic movements, followed by loss of consciousness. Computed tomographic scan with contrast demonstrated a giant aneurysm of the middle cerebral artery with adjacent cerebral edema, contrast uptake into the aneurysm, and an adjacent region in which a thrombus has formed. The patient underwent successful craniotomy, with thrombectomy and aneurysm clipping.

Status epilepticus due to the reperfusion syndrome. A 66-year-old woman underwent an otherwise uncomplicated right carotid endarterectomy for asymptomatic extracranial carotid artery disease 3 days earlier. She awoke with a headache, followed by left-arm clonic movements. These progressed to generalized, tonic-clonic seizures, which were not aborted by administration of lorazepam and phenytoin sodium therapy. The continuous electroencephalographic (EEG) monitor showed periodic lateralized epileptiform discharges occurring every 2 to 5 minutes, lasting a few seconds (A). Subsequent T2- and diffusion-weighted magnetic resonance imaging studies of the brain showed right-sided thalamic (B) and cortical lesions (C). Phenobarbital sodium was then administered, which arrested seizure activity. Ref indicates reference.
