A 9-year old boy has seizures characterized by staring, sudden impairment of consciousness with complete unresponsiveness, and pause in ongoing activity lasting 20 seconds. The EEG shows 3Hz spike-wave discharge. About 6 seconds after the onset of the EEG discharge, he has mild myoclonic twitching of eyelids, which persists for a few seconds. His seizure is best classified as this type.

A 6-year-old, right-handed boy with mild developmental delay and sensory integration disorder presents with intractable epilepsy. His seizures consist of throat clearing, unpro- voked laughter, and postictal confusion. Neurological examination was nonfocal. MRI was normal. Ictal EEG showed initial, rhythmic, left frontotemporal fast activity with rapid spread to bilateral fronto-central regions. An ictal single photon emission computer tomography (SPECT) scan was performed as shown in the following, with the injection administered within 10 seconds of seizure onset. Where is the seizure focus?

A 1-year-old girl presents with intractable epilepsy. She was born at full term and was noted to have an extensive port wine stain over the right side of her face. At 6 weeks of age, she was diagnosed with epilepsy after she had focal motor seizures. Currently, she continues to have daily seizures despite treatment with four antiepileptic drugs (AEDs) and aspirin. On exam, she has moderate left upper extremity weakness and right gaze preference. An axial, postcontrast, T1 image of her MRI is shown. Which of the following statements describes her diagnosis and the best treatment option?

A. She has right occipital cavernoma and stereotactic thermal laser ablation is indicated

B. She has Sturge–Weber syndrome (SWS) and functional hemispherectomy is indicated

C. She has leptomeningeal carcinomatosis, and biopsy and chemotherapy are indicated

D. She has right occipital arteriovenous malformation (AVM) and radiosurgery is indicated

B. She has Sturge–Weber syndrome (SWS) and functional hemispherectomy is indicated
