Bailey and Cushing described the oligodendroglioma firstly in 1926. The oligodendroglioma is rare tumor and involves the ventricular system in 7% to 10% of all cases. The authors present a case of intraventricular oligodendroglioma associated with arterio venous malformations in a 34 year old male who had the history of visual disturbance and mental deterioration, for one month. The diagnosis was comfirmed by operation and autopsy.

나중환,김영수,도종웅,이규웅 대한신경외과학회 1979 Journal of Korean neurosurgical society Vol.8 No.1

We have recently experienced a rare case of extradural epidermoid cyst in the left middle cranial fossa associated with trigeminal neuralgia. A 22-year old female has intermittently developed lancinating pain in the left of face and dark reddish rhiorrhea for 5 years. Plain skull films showed an elevation of lesser wing of sphenoid bone and portrusion of left zygomatic arch with deepening of left middle cranial fossa. Carotid angiograms and brain scan with techinecicum 99m revealed a large cystic mass in left middle cranial fossa. A left temporal craniotomy was done and a large cystic mass filled with dark bluish colored fluid was removed at the left middle cranial fossa. Postoperatively the trigeminal neuralgia subsided completely. We have discussed the pathogensis and clinical symptoms with the review of the literatures.

To evaluate the epidemiological and clinical status of cerebrovascular disease in Chung Ju area, authors have studies 224 cases of stroke patients who have been treated in Kon Kuk University Hospital from April, 1989 to March, 1991. This study have been performed by department of Neurology and Neurosurgery co-operatively. The results were as follows : 1) The ischemic stroke(54.0%) was more common than hemorrhage stroke(41.5%), and thrombotic infarction was the most frequent type(29.5%). 2) The incidence was highest in 6th and 7th decades. Female was more commonly affected(51.8%). Male was more vulnerable to ischemic stroke, while female to subarachnoid hemorrhage. In seasonal prevalence, during autumn and winter time stroke was predominant. 3) In preceding disease, hypertention was most common and previous stroke was the next. Sleep, physical work, rest and meal were the leading causes of the precipitating factors in order. Initial symptoms were altered mentality, hemiparesis, headache, dizziness, speech disturbance in order. 4) On plain chest X-ray, 67.4% was abnormal. Among them, hypertensive heart was the most common abnormal finding. On EKG, 78.6% was abnormal and LVH, myocardial ischemia, atrial fibrillation were the findings in order. 5) The overall mortality rate 18.8%. The highest mortality rate was found in subarachnoid hemorrhage. The ischemic stroke group had a better prognosis. 6) Above results suggest that needs of institution of stroke clinic where multidepartments are participated. That clinic may take the role of more advanced treatment and educating local people for prevention and rehabilitation of stroke patients.

A case of mult-ple intracranial aneurysms associated with interrupted aortic arch is reported. Angiogram showed internal carotid artery bifurcation aneurysm and middle cerebral artery aneurysm. Cardiac cineangiogram revealed the interrupted aortic arch. Systemic diseases associated with multiple intracranial aneurysms and their pathophysiology are discussed and the pertinent literature is reviewed.

고혈압성 피각출혈에서 예후를 보인 전산화 단층촬영 소견

Computed tomographic findings were analyzed in 46 patients with hypertensive putaminal hemorrhage accompainied by hemiparesis. It has been important prognostic index whether to involve or not to involve posterior limb of internal capsule. To study the reason for this, the relationship between the extent of a hematoma and the level at which the pyramidal tract was destroyed was investigated. From the consideration of the process of destruction of the pyramidal tract by a hematoma, it seemed that computed tomographic findings at the level of the body of the lateral ventricle rather than at the level of the posterior limb of the internal capsule were of value in evaluating the prognosis of hemiparesis.

외상성 뇌천막주위 혈종

김영수,임호영,나중환,도종웅,장경식 대한신경외과학회 1986 Journal of Korean neurosurgical society Vol.15 No.3

A clinical analysis of unusual sited traumatic subural hematomas are presented and discussed. These disorders are rare form of intracranial hemorrhage. Commonly, acute subdural hematoma is located in the cerebral convexity, which shows a cresent-shaped increased density on axial Brain CT scan. A conventional axial CT scan is difficult to detect the tentorial subdural hematoma because of artifact of petrous pyramid. So coronal CT scan is prefered diagnostic procedure. This hematoma is originated from a bridging vein at the edge of a tetorial or falx-tentorial junctional tear. Interhemispheric subdural hematoma is originated from a bleeding of bridging vein between the superior saggital sinus and cerebral cortex. Conservative treatment for above hematoma may be beneficial unless neurological deterioration necessitates early operative procedure.

Digital infrared thermographic imaging system is noninvasive, easy to reading, objective and physiologic instrument by measuring and imaging infrared energy emitted from skin surface. The authors present the result of digital infrared thermographic images of 83 patients of operated lumbar disc herniation from October, 1990 to March, 1991. 46 patients have received discectomy and the other 37 patients have received chemonucleolysis. We have done digital infrared thermographic imaging preoperatively and postoperatively. In preoperative digital infrared thermographic imaging, diagnostic sensitivity is about 76%. In postoperative digital infrared thermographic imaging, clinical results were well correlated in discectomy group. But in chemonucleolysis group, clinical results were not correlated with digital infrared thermographic images.
