  • The purpose of this study is to find out the relationships of brain laterality, active EEG over all brain regions and personality traits by measuring EEG signals on the basis of the counseling psychology personality theories. For this study, the EEG of ninety-six college students as measured by an eight channel EEG device and analyzed through the computer and the data of their Big Five Personality Test were analyzed by statistical analysis. The result was that when theta's laterality at the prefrontal lobe is bigger, neuroticism is higher in the personality factors. On each of the brain regions, theta's activity on the left of the prefrontal lobe makes higher neuroticism but lower conscientiousness, and beta's activity on the left of the frontal lobe makes lower extroversion and openness to experience. These results showed that there are statistically meaningful relationships between the brain region activated specific EEG and individual personality or psychological traits. This study branched out into theta band while most previous studies measured in alpha and beta band. Also from these results it suggested the counseling strategy with the brain and follow-up studies.

  • Metronidazole-induced encephalopathy is a very rare complication of the long standing use of metronidazole. The encephalopathy is bilateral and symmetric in nature. We report on the magnetic resonance imaging (MRI) and clinical course of metronidazole-induced encephalopathy in a 60-year-old female with a persistent anaerobic brain abscess after draining of the abscess. After 3 months of metronidazole administration, the patient complained of dysarthria, tingling sense of all extremities, and left hemiparesis. MRI revealed symmetric hyperintensity lesions in medulla, pons, dentate nuclei of cerebellum, and splenium of corpus callosum, all of which represent typical findings of metronidazole-induced encephalopathy. In addition, asymmetric lesions in midbrain, thalamus, putamen and cerebral subcortical white matter were noted. The patient recovered after discontinuation of metronidazole and the remaining abscess was successfully treated with meropenem and levofloxacine.

  • Primary anaplastic oligodendroglioma in brain stem is extremely rare. The authors present a case of a anaplastic oligodendroglioma arising from pons. A 29 year-old male patient was admitted because of cranial nerve palsy and visual disturbance. Neurological examination revealed bilateral sixth and left seventh cranial nerve plasies. Near-total resection of tumor mass was performed through midline suboccipital appraoch. Tumor was not related with choroid plexus and major vessels but it was firmly attached to the fourth ventricle floor. Tumor was considered to be arised from the tegmental portion of pons, growing dorsally into the 4th ventricle. Hitopathological exmination revealed primary anaplastic oligodendroglioma. Postoperative course was uneventful. The authors believe that this type of tumor with dorsally growing pattern can be successfully resected without major neurological deficit.

  • Objectives : Obsessive-compulsive(OC) symptoms have yet to be directly studied in neurodegenerative conditions involving behavioral changes. To examine regional abnormalities in the brains of dementia patients with OC symptoms, we assessed the gray matter density using voxel-based morphometry(VBM). Methods : We performed brain magnetic resonance imaging(MRI) with VBM analysis in 106 dementia patients with OC behaviors. In this study, OC behaviors were investigated in patients with neurodegenerative disease using the modified Manchester Behavior Questionnaire. Results : The OC behavior scores were correlated with structural brain volume using VBM. The total OC symptom score correlated negatively with the volume of both putamens, the right middle orbitofrontal gyrus, both anterior cingulate cortices, and the left insula(p<0.001, uncorrected). No gray matter reductions were associated specifically with the OC symptom sub-categories. Conclusions : Our results suggest that abnormalities in these brain regions may play an important role in the pathophysiology of OCD in neurodegenerative disease. This is the first lesion study to investigate the neural basis of OCD behaviors in neurodegenerative disease.

  • A 20-month-old boy presented with a intraparenchymal mass in the right frontoparietal area manifesting as complex partial seizure, secondary generalization and left hemiparesis. Magnetic resonance images (MRI) of the brain showed inhomogeneously enhancing mass in the right frontoparietal area which has irregular margin and perilesional edema. Based on the radiological findings, a preoperative diagnosis was an intraaxial tumor, such as pilocytic astrocytoma or dysembryoplastic neuroepithelial tumor. The patient underwent a surgery including frontal craniotomy. The tumor had a partially extreme adherence to the surrounding brain tissue but it showed no dural attachment. Gross-total resection of the tumor was achieved. Postoperative follow-up computed tomography scans showed no residual tumor. The pathological findings confirmed the tumor as a WHO grade I meningioma, transitional type. Nine months after the surgery, follow-up brain MRI showed no recurrence of the tumor, porencephaly in site where the tumor was resected; the patient's symptoms had fully recovered. We report the case of a meningioma in a 20-month-old boy.

  • The authors present a case of 68-year-old woman who underwent resection of a metastatic adenocarcinoma in the left parietooccipital area. The intraoperative course was uneventful; however, after closure of the scalp incision, increased bleeding from the suture line was noted. A computerized tomography scan that was performed immediately after operation revealed acute epidural hemorrhage with mass effect under the bone flap. The patient developed disseminated intravascular coagulation and immediate re-exploration was performed. This patient was successfully treated owing to early recognition of the condition and immediate treatment with transfusion. Neurosurgeons should be alert that hypercoagulabe state is common in cancer patients and consumptive coagulopathy can occur after resection of metastatic brain tumor.

  • The purpose of the present study was to explore the proper method for animal stroke model of Oriental medicine To this end, brain ischemia was induced by distal middle cerebral artery occlusion(dMCAO) and proximal middle cerebral artery occlusion(pMCAO) and evaluated with the method of Triphenyl Tetrazolium Chloride (TTC) staining and Swimming Behavior Test. Results demonstrated that first, infarct size and volume of pMCAO group were significantly bigger that those of dMCAO group. Second, analysis of swimming behavior test revealed that the percentage of left turning angles of pMCAO was significantly bigger than that of dMCAO. Third, during swimming behavior test, there were peculiar traces of small successive circles that represent motor dysfunction and conscious disturbance among dMCAO group. The results of the study thus indicate that non-invasive intraluminal method of pMCAO was the appropriate animal stroke model for Oriental medicine in the light of brain ischemia as hemiplesia and conscious disturbance.

  • Takayasu’s disease produces the occlusive and aneurysmal lesions of major branches of the aorta. Angiography is the most important diagnostic procedure in Takayasu’s disease. Surgical treatment is often justified to avoid the possible lethal consequences of hypertension on the heart, kidney, and brain, as well as in the case of aneurysm because of its risk of rupture. We experienced one case of the Takayasu’s disease associated with abdominal coarctation and renovascular hypertension. The patient was 17 years old female and had suffered from hypertension for 14 months. On physical examination, BP was 150/100 mmHg in the right arm and 120/80 mmHg in the left arm. The pulses of the left brachial and femoral arteries were weakly palpable. Aortogram showed the stenosis of the left common and subclavian arteries, coarctation of the abdominal aorta, and stenosis of the right renal artery and complete occlusion of the left renal artery. The stenosis of the right renal artery and the occlusion of the left renal artery produced the renovascular hypertension. She underwent aorta-aortic bypass for the coarctation of the abdominal aorta and aorta-renal bypass for treatment of renovascular hypertension Postoperatively, both femoral pulses were equally palpable. On discharge, antihypertensive drugs were discontinued. She has remained normotensive for last one year.
