ABSTRACT
Treatment of cerebral aneurysms poses a risk of cerebral hemorrhage and/or ischemia; these potential sequelae are usually associated with changes in intraoperative neurophysiologic monitoring (IONM) modalities. Our case demonstrates a patient with significant changes in IONM during the treatment of a right posterior cerebral artery aneurysm who did not develop neurologic deficits until three days postoperatively. IONM changes can represent a guide in postoperative patient management and may pose grounds for closer monitoring of patients with IONM changes that do not develop immediate postoperative deficits.

Coexistence of 2 idiopathic epilepsy syndromes (ie, childhood absence and Rolandic epilepsy), as evidenced by electroencephalographic (EEG) findings with or without clinical features of the 2 conditions, is uncommon and remains controversial. Few case reports support this coexistence either as a continuum or drug-induced conversion, whereas a large sample case review did not find such co-occurrence. The authors report a case of conversion of typical absence to Rolandic spikes after treatment with ethosuximide. An 11-year-old girl was diagnosed with typical childhood absence epilepsy at the age of 6 years with classic clinical and EEG features. She became seizure-free on ethosuximide but her follow-up EEGs consistently recorded right centrotemporal and centroparietal spikes without associated clinical seizures. This case may suggest simultaneous presence of these 2 common childhood idiopathic epilepsies either as a continuum or a drug-induced conversion.

Ictal asystole is a presumably rare but potentially fatal complication of seizures, most often of temporal lobe origin. It is believed that at least some cases of sudden unexplained death in epilepsy (SUDEP) might be triggered by ictal bradycardia or asystole. Current standard practice is to implant a permanent pacemaker in these patients to prevent syncope and/or death. However, emerging data suggests that effective medical or surgical treatment of epilepsy might be enough to prevent cardiac asystole, eliminating the need for permanent pacemaker placement. We describe a case of new onset left frontal lobe epilepsy in a young athletic patient who presented with near-syncopal episodes but whose comprehensive work-up revealed frequent events of ictal bradycardia and asystole. He responded well to monotherapy using oxcarbazepine, avoiding a permanent pacemaker.
