  • We present a recordings of 37-year-old woman with simultaneous ictal scalp and subdural electrodes. The ictal rhythm on subdural electrocorticography (ECoG) started earlier (median 24.5 sec) and ended later (median 2.0 sec) compared to ictal rhythm on scalp EEG. Eight ictal ECoG recordings were well localized to left temporal area, whereas ictal scalp EEG recordings were not. Our case shows the obvious timing relations between two recordings, and different electrophysiologic information about localization of ictal onset zone.

  • 목 적 : 영아연축은 이차성 전신간질중의 하나로 간질 병소를 발견하기 힘든 질환중의 하나이다. 이에 저자들은 $^{99m}Tc-ECD$ 추적자의 느린 점적 주사를 이용한 발작기 SPECT를 통하여 영아 연축 환아에서 간질 병소를 찾아보고자 하였다. 방 법 : 2005년 3월부터 2007년 2월까지 연세대학교 의과대학 소아과에 내원한 영아 연축 14명의 환아를 대상으로 첫 연축이 발생하는 시점에 $^{99m}Tc-ECD$ 를 2분에 걸쳐 천천히 같은 속도로 주입하였다. 발작간기와 발작기 간의 SPECT 의 차이를 비교하였으며 객관적인 비교를 위하여 SISCOM기법을 사용하였다. 또한 간질 병소를 발견할 수 있는 진단기법인 뇌파, 자기공명영상, 양전자단층촬영(PET) 등과 비교 분석하였다. 결 과 : 전체 14례의 추적자의 느린 점적 주사를 이용한 발작기 SPECT 중 10례에서 간질 병소의 혈류가 증가하였다. 비디오 뇌파와 발작기 SPECT에서 간질병소의 일치율은 Kappa=0.57, 95% confidence interval: 0.18-0.96로 높게 나왔다. 이 중 6례에서 발작기 SPECT와 비디오 뇌파에 근거하여 간질 수술을 시행하였으며 수술적 예후가 Engle class I으로 좋은 결과를 보였다. 결 론 : 추적자의 느린 점적 주사를 이용한 발작기 SPECT는 간질 병소를 찾기 어려운 영아 연축 환아에서 간질 병소를 찾아내는데 중요한 역할을 하는 것을 알 수 있었다. 그러나 보다 큰 규모의 전향적인 연구가 필요할 것으로 사료된다.

  • 배뇨 유발 반사발작은 매우 드물며, 문헌상에서 단지 8례가 보고되었으며, 발작기 뇌파로 진단한 예는 국내에서 보고된 바 없다. 7세 남아가 이차전신화 부분발작을 주소로 내원하였다. 발작은 단지 배뇨 수초 후에 시작되었으며 손의 자동증과 함께 비틀거리며 쓰러지면서 의식소실과 함께 이차적으로 전신 강직 발작을 하였다. 발작기 뇌파에서 왼측 전두부와 측두부에서 다극서파가 보이다가 오른쪽 전두부와 측두부로 퍼져나가는 소견을 보여 배뇨 유발성 이차 전신화 부분발작으로 진단되어 보고하는 바이다.

  • Seizure can be categorized in various ways. Seizures are divided into those that are generalized and those affecting only part of the brain (focal seizure). Focal (partial) seizures are subdivided into simple seizures and complex seizures. Simple focal seizures may be manifested by focal motor, sensory or autonomic symptoms and consciousness is preserved. The above symptoms may be preceded, accompanied or followed by, and consciousness is impaired in, complex focal seizures. Ictal aphasia can arise from epileptiform discharge on cortical language areas. Generally next to the ictal aphasia, generalized seizures occur, but without losing consciousness, only aphasia takes place. A 61-year-old woman was admitted due to ictal aphasia and facial spasm, and she showed a little palpitation and was startled easily. We diagnosed her as Shimdamgiheo (心膽氣虛) and Damhwashimyo (痰火心擾), so we prescribed Chungsimondam-tang. It was effective on that case. so we report.

  • Correct localization of epileptogenic zone is important for the successful epilepsy surgery. Both ictal perfusion single photon emission computed tomography (SPECT) and interictal F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) can provide useful information in the presurgical localization of intractable partial epilepsy. These imaging modalities have excellent diagnostic sensitivity in medial temporal lobe epilepsy and provide good presurgical information in neocortical epilepsy. Also provide functional information about cellular functions to better understand the neurobiology of epilepsy and to better define the ictal onset zone, symptomatogenic zone, propagation pathways, functional deficit zone and surround inhibition zones. Multimodality imaging and developments in analysis methods of ictal perfusion SPECT and new PET ligand other than FDG help to better define the localization.

  • 목적: 후두엽 간질에서 발작간기 F-18-FDG PET와 발작기 SPECT의 간질원인병소 굴소화 및 편측화 진단성능을 조사하였다. 대상 및 방법: 침습적 뇌파검사와 수술과 수술 후 경과를 관찰하여 후두엽 간질로 진단된 17명의 환자를 대상으로 발작간기 F-l8-FDG PET (15명)와 발작기 뇌관류 Tc-99m-HMPAO SPECT를 시행하였다. 대사가 감소된 부분과 관류가 가장 증가된 곳을 간질원인병소로 진단하고 후두엽 병소를 제대로 진단한 경우 국소화에 병소쪽 반구의 다른 엽 또는 여러 엽을 지칭한 경우에 편측화에 성공하였다고 보아 국소화율과 편측화율을 조사하였다. 결과: F-18-FDG PET는 15명 중 9명(60%)에세 병측 후두엽을 국소화하였고 14명 (93%)을 편측화하였다. 발작기 뇌관류 SPECT는 17명 중 3명(18%)에서 국소화하였고 13명(76%)에서 편측화하였다. 자기공명영상에 병변이 발견되지 않았거나 발작기 SPECT가 정화하게 국소화하지 못한 경우에 추가적인 국소화 및 편측화 정보를 F-18-FDG PET에서 얻을 수 있었던 경우가 각각 5명, 8명이었다. 결론: 후두엽간질에서 발작기 뇌관류 SPECT로 병변쪽 반구를 편측화할 수 있었으나 F-18-FDG PET는 국소화와 편측화에 뛰어나 자기 공명영상에 병변이 발견되지 않는 경우를 포함하여 간질원인 병소를 찾는 데 크게 도움이 되었다.

  • The most significant factor in pathogenesis of vascular headaches like migraine and cluster headache is dynamic changes of diameters of the cerebral arteries. TCD is a valuable noninvasive tool to assess the cerebral hemodynamic status by measuring the flow velocities of the intracranial cerebral arteries around the circle of Willis. TCD can evaluate flow velocities and vasoreactivity of the patients with a vascular headache during the ictal phase as well as during intericatal phase. Distribution of the changes recorded differ between types of headaches and also between the major ictal symptoms. The changes suggest the presence of prolonged vasospasm interictally and more marked relaxation of the cerebral arteries. TCD can be used to monitor the long-term clinical course of patients with vascular headache by correlation the symptomatic improvement and TCD data before and after long-term pharmacological prophylactic treatments. During the ictal phases large intervention. The results may be used in selecting and evaluating the agents for abortive therapy for acute attacks. In conclusion TCD can quantitatively evaluate vascular headaches when making diagnosis and classification and can provide guidelines to choose more individualized therapeutic options for both acute and long-term treatment.

  • Even though the origin and nature of nocturnal paroxysmal dystonia (NPD) remains unclear, it has been considered as a manifestation of the nocturnal frontal lobe epilepsy. We report a 17-year-old man with abnormal stereotyped movement during sleep. Video-EEG monitoring, ictal SPECT and night polysomnography did not show any evidence of epilepsy. However, the partial response to large dose of carbamazepine and the scoring according to the frontal lobe epilepsy and parasomnias (FLEP) scale suggest his events could be classified as epilepsy. Therefore we think the FLEP scale might be a useful tool for differential diagnosis in a patient presenting NPD.

  • Purpose: To investigate ictal hyperperfusion patterns during semiologic progression of seizures, we performed SPECT subfraction in 50 patients with temporal lobe epilepsy (TLE). Materials and Methods: The patients were categorized Into five groups according to semiologic progression during ictal SPECT (group-1 having only aura; group-2 haying motionless staling with or without aura; group-3 having motionless staring and then automatism with or without aura; group-4 having motionless staring and then dystonic posturing with or without aura and automatism; group-5 having motionless staring, automatism, then head version and generalized seizures with or without aura and dystonic posturing). Results: In group-1, three patients showed ipsilateral temporal hyperperfusion and two had bilateral temporal hyperperfusion with ipsilateral predominance. In group-2, three (42.9%) patients showed bilateral temporal hyperperfusion with unilateral predominance and four (57.1%) revealed insular hyperperfusion of epileptic side. In group-3, 15 patients (88.2%) showed bilateral temporal hyperperfusion with unilateral predominance and 12 (70.6%) insular hyperperfusion. In group-4, 11 patients (84.6%) showed basal ganglia hyperperfusion on the opposite hemisphere to the side of the dystonic posturing. en group-5, there were multiple hyperperfusion areas in the frontal, temporal and basal ganglia regions. However, the injection times of radiotracer in five groups were relatively short and similar. Conclusions: The semiologic progression in TLE seizures were related to the propagation of hyperperfusion from ipsilateral temporal lobe to contralateral temporal lobe, insula, basal ganglia, and frontal lobe. Not only the radiotracer injection time but also semiologic progression after the Injection was significant in determining hyperperfusion pattern of ictal SPECT.
