We report a case of a 5-year-old girl who developed left hemiparesis and left facial palsy, 6 days after the initiation of fever and respiratory symptoms due to pneumonia. Chest radiography, conducted upon admission, showed pneumonic infiltration and pleural effusion in the left lung field. Brain magnetic resonance imaging showed acute ischemic infarction in the right middle cerebral artery territory. Brain magnetic resonance angiography and transfemoral cerebral angiography revealed complete occlusion of the right middle cerebral artery. Mycoplasma pneumoniae infection was identified by a 4-fold increase in IgG antibodies to M. pneumoniae between acute and convalescent sera by enzyme-linked immunosorbent assay. Fibrinogen and D-dimer levels were elevated, while laboratory exams in order to identify other predisposing factors of pediatric stroke were all negative. This is the first reported pediatric case in English literature of a M. pneumoniae-associated cerebral infarction involving complete occlusion of the right middle cerebral artery.

Objective : We retrospectively evaluated the prognostic factors that can influence long-term survival in patients who suffered acute large cerebral infarction. Methods : Between June 2003 and October 2008, a total of 178 patients were diagnosed with a large cerebral infarction, and, among them, 122 patients were alive one month after the onset of stroke. We investigated the multiple factors that might have influenced the life expectancies of these 122 patients. Results : The mean age of the patients was $70{\pm}13.4$ years and the mean survival was $41.7{\pm}2.8$ months. The mean survival of the poor functional outcome group ($mRS{\geq}4$) was $33.9{\pm}3.3$ months, whereas that of the good functional outcome group ($mRS{\leq}3$) was $58.6{\pm}2.6$ months (p value=0.000). The mean survival of the older patients (270 years) was $29.7{\pm}3.4$ months, whereas that of the younger patients (<70 years) was much better as $58.9{\pm}3.2$ months (p value=0.000). Involvement of ACA or PCA territory in MCA infarction is also a poor prognostic factor (p value=0.021). But, other factors that are also known as significant predictors of poor survival (male gender, hypertension, heart failure, atrial fibrillation, diabetes mellitus, a previous history of stroke, smoking, and dyslipidemia) did not significantly influence the mean survival time in the current study. Conclusion : Age (older versus younger than 70 years old) and functional outcome at one month could be critical prognostic factors for survival after acute large cerebral infarction. Involvement of ACA or PCA territory is also an important poor prognostic factor in patients with MCA territorial infarction.

Objective : Stroke is the most prevalent disease involving the central nervous system. Since medical modalities are sometimes ineffective for the acute edema following massive infarction, surgical decompression may be an effective option when medical treatments fail. The present study was undertaken to assess the outcome and prognostic factors of decompressive surgery in life threatening acute, severe, brain infarction. Methods : We retrospectively analyzed twenty-six patients (17 males and 9 females; average age, 49.7yrs) who underwent decompressive surgery for severe cerebral or cerebellar infarction from January 2003 to December 2006. Surgical indication was based on the clinical signs such as neurological deterioration, pupillary reflex, and radiological findings. Clinical outcome was assessed by Glasgow Outcome Scale (GOS). Results : Of the 26 patients, 5 (19.2%) showed good recovery, 5 (19.2%) showed moderate disability, 2 (7.7%) severe disability, 6 (23.1%) persistent experienced vegetative state, and 8 (30.8%) death. In this study, the surgical decompression improved outcome for cerebellar infarction, but decompressive surgery did not show a good result for MCA infarction (30.8% overall mortality vs 100% mortality). The dominant-hemisphere infarcts showed worse prognosis, compared with nondominant-hemisphere infarcts (54.5% vs 70%). Poor prognostic factors were diabetes mellitus, dominant-hemisphere infarcts and low preoperative Glasgow Coma Scale (GCS) score. Conclusion : The patients who exhibit clinical deterioration despite aggressive medical management following severe cerebral infarction should be considered for decompressive surgery. For better outcome, prompt surgical treatment is mandatory. We recommend that patients with severe cerebral infarction should be referred to neurosurgical department primarily in emergency setting or as early as possible for such prompt surgical treatment.

Background: Acute cerebral infarction is a major risk factor for postoperative neurologic complications in cardiac surgery. However, the outcomes associated with acute silent cerebral infarction (ASCI) have not been not well established. Few studies have reported the postoperative outcomes of these patients in light of preoperative Diffusion-weighted magnetic resonance imaging (DWI). We studied the postoperative neurologic outcomes of patients with preoperative ASCI detected by DWI. Methods: We retrospectively studied 32 patients with preoperative ASCI detected by DWI. None of the patients had preoperative neurologic symptoms. The mean age at operation was $68.8{\pm}9.5$ years. Five patients had previous histories of stroke. Four patients had been diagnosed with infective endocarditis. Single cerebral infarct lesions were detected in 16 patients, double lesions in 13, and multiple lesions (>5) in three. The median size of the infarct lesions was 4 mm (range, 2 to 25 mm). The operations of three of the 32 patients were delayed pending follow-up DWI studies. Results: There were two in-hospital mortalities. Neurologic complications also occurred in two patients. One patient developed extensive cerebral infarction unrelated to preoperative infarct lesions. One patient showed sustained delirium over one week but recovered completely without any neurologic deficits. In two patients, postoperative DWI confirmed that no significant changes had occurred in the lesions. Conclusion: Patients with preoperative ASCI showed excellent postoperative neurologic outcomes. Preoperative ASCI was not a risk factor for postoperative neurologic deterioration.

Stenting is a useful alternative treatment modality in carotid artery stenosis patients who are too high-risk to undergo carotid endarterectomy (CEA). We report a case of contralateral cerebral infarction after stenting for extracranial carotid stenosis. A 78-year-old woman was admitted to the hospital with left-sided weakness. Based on magnetic resonance imaging (MRI) of the brain and conventional angiography, she was diagnosed with an acute watershed infarct of the right hemisphere secondary to severe carotid stenosis. Stenting was performed for treatment of the right carotid artery stenosis after a one-week cerebral angiogram was completed. Thirty minutes after stent placement, the patient exhibited a generalized seizure. Four hours later, brain MRI revealed left hemispheric cerebral infarction. Complex aorta-like arch elongation, tortuosity, calcification, and acute angulation at the origin of the supra-aortic arteries may increase the risk of procedural complications. In our case, we suggest that difficult carotid artery catheterization, with aggressive maneuvering during stenting, likely injured the tortuous, atherosclerotic aortic arch, and led to infarction of the contralateral cerebral hemisphere by thromboemboli formed on the wall of the atherosclerotic aorta.

급성 뇌졸중의 경우 빠른 시간 내의 진단과 치료가 예후에 큰 영향을 미친다. 본 연구에서는 초급성기 뇌경색 환자에서 관류CT와 확산강조MRI의 영상을 비교하여 허혈 부위와 경색부위에 나타나는 차이점을 알아보고자 하였다. 뇌관류 CT와 확산강조 자기공명영상(diffusion weighted MR imaging, DW-MRI)을 시행한 12명의 급성뇌경색 환자를 대상으로 병변부위와 정상부위에서 각각의 CBF, CBV, MTT, TTP지도와 DW-MRI의 신호강도 값을 비교하고, 관류CT와 DW-MRI에서 병변의 크기 비교를 해보았다. CBF, CBV, MTT, TTP는 모두 관류결손을 보였고, 관류 결손이 인지되는 부위에서 MTT와 TTP시간의 현저한 지연이 있었다. 뿐만 아니라, MTT와 TTP 지도의 결손부위 면적은 DW-MRI 보다 크게 나타나 허혈성 반음영을 추측할 수 있었고, 일부 DW-MRI에서 경색부위를 나타내지 못하는 경우도 있었다. 결론적으로 관류 CT의 지도를 이용하면 뇌경색의 조기 진단뿐만 아니라 허혈 중심부, 그리고 허혈성 반음영을 예측하여 관류결손 부위의 혈류 역학적 상태를 평가 할 수 있어 보다 효과적인 치료계획을 세울 수 있다.

임상적용 전 단계에서 마우스와 같은 작은 설치류를 이용한 신경학적 실험의 필요성이 높아지면서 임상용 3T MRI를 이용한 마우스 뇌 영상의 요구가 높아지고 있다. 본 연구에서는 임상용 3T MRI를 이용한 마우스 뇌 영상의 가능성과 기술적인 적용과 최적화에 대해 알아보고자 하였다. 20~25g 체중 마우스 3마리에서 임상용 3T MRI를 이용하여 T1 강조영상(T1WI), T2 강조영상(T2WI), FLAIR (Fluid Attenuated Inversion Recovery) 영상, 가돌리늄 조영 T1 강조영상(Gd-T1WI), 확산 강조영상(DWI)을 시행하였다. 대상이 되었던 마우스 1마리는 뇌 경색을 유발시키지 않았으며 2마리는 우측 중대뇌동맥을 결찰하여 일측 뇌경색을 유발하고 1시간, 24시간, 72시간에 각각의 MRI 영상을 시행하였으며 각 영상에서 마우스 뇌의 striatum, 뇌실, 대뇌 피질의 해부학적 구별, 뇌 경색 부위의 진단 가능성 등을 분석하였다. T2WI에서 마우스 뇌의 striatum, 뇌실, 대뇌 피질의 해부학적 구별이 모두 가능하였고 T1WI, FLAIR, DWI 영상에서는 위의 해부학적 경계부위의 해상도는 감소하였다. 뇌경색 부위는 경색 후 1시간, 24시간, 72시간 영상 모두에서 발견되었고 T2WI, FLAIR에서는 24시간, 72시간에서만 구분되었다. 임상용 3T MRI를 이용한 마우스 뇌 영상에서 해부학적 부위의 구별이 가능하였고 특히 DWI를 이용하여 급성기 뇌 경색의 진단이 가능하였다. 앞으로 기술적인 적용과 최적화를 위한 노력이 계속 진행된다면 임상 실험에 큰 도움을 줄 수 있을 것이라 생각된다.

Fibromuscular dysplasiais an uncommon condition of idiopathic, non-inflammatory and non-atherosclerotic disease of the musculature of arterial walls. The disease is rare, but it commonly affects young and middle aged women. Isolated intracranial cerebral fibromuscular dysplasia is extremely rare because cerebral fibromuscular dysplasia usually affects extracranial vessels. A 20-year-old woman was admitted with light hemiplegia and global aphasia. Brain MRI and MRA demonstrated acute left middle cerebral artery territory infarction with a multifocal stenosis and dilatation of the left middle cerebra artery and left internal carotid. The characteristic conventional cerebral angiographic findings demonstrated a typical string-of-beads appearance in the left distal internal carotid artery and proxiaml portion of the left middle cerebral artery, which suggested a medial type fibromuscular dysplasia. We report a case of isolated intracranial fibromuscular dysplasia with left middle cerebral artery territory infarction. Fibromuscular dysplasia should he considered as a stroke risk factors in children and young adults, especially in patients with no known cardiovascular risk factors.
