Dandy-Walker cyst 1예

정헌화,김상철,정상섭,이헌재 대한신경외과학회 1974 Journal of Korean neurosurgical society Vol.3 No.1

In 1921, Dandy discussed the clinical diagnosis and treatment of hydrocephalus secondary to occlusion of the foramina of Magendie and Luschka. In 1944, Walker reported a case of congenital atresia of the outlets of the fourth ventricle treated surgically. Since a detailed study of this disease entity by Benda in 1954, the condition has commonly been known by the term, the Dandy-Walker syndrome. In 1968, Raimondi and et al refered this condition as the Dandy-walker cyst. There is considerable discussion as to the nature of the fundamental embryologic error in this condition, but Benda suggested that atresia of developing fourth ventricular foramina was only a part of the syndrome and not its cause, because in some cases reported, the foramina were found to be patent. These patients. show characteristic clinical symptoms, signs and radiological findings and should suggest the correct diasnosis. This syndrome was one of the first cause of hydrocephalus to be treated successfully by surgery. We are reporting one case of this cyot encountered recently at Yonsei University Medical Center.

척수의 악성 흑색종 1예

Malignant melanoma of the spinal cord is a rare tumor. The melanomas that originate in the meninges bear a general structural resemblance to those arising elsewhere, but it is questionable whether they ever metastasis outside the central nervous system. If can be also argued that the primary central nervous system melanoma could actually be a metastasis from an occult primary site in the skin, esophagus, rectum or other sites. We are reporting a case of malignant melanoma involving the cervical spinal meninges and hard palate.

뇌혈관 촬영상 후대뇌동맥과 후교통동맥의 출현에 대한 조사

Carotid angiography is a most important diagnostic procedure for investigation of intracranial lesions and for understanding the cerebral circulation. Of the cerebral arteries, only the posterior cerebral artery is, both functionally and anatomically, a border artery between the carotid and vertebral circulatory systems, so it is more important for an understanding of the cerebral circulation. Early in the development of the fetal circulation, the posterior cerebral artery arises from the internal carotid artery (carotid segment), with the connection to the basilar artery (basilar segment) developing later. In many cases, however, it derives its supply from both systems simultaneously. Angiographic demonstration of the posterior cerebral artery is influenced by certain pressure factors of the intracranial cavity and other technical factors, for example, site of puncture, needle size, injection time and force used and position of the head, etc. Here the author has analysed the factors of age, sex. puncture site and right or left side and a degree of hydrocephalus. Carotid angiography has been performed for definite indication, hence, no cerebral angiography has been performed on any entirely asymptomatic subject. The normal controls used in this investigation consist of angiographies done in subjects with symptoms but no evidence of vascular lesions or other abnormality. The author found a high incidence of the posterior cerebral arteries demonstrated in hydrocephalus, in spite of increased intracranial pressure and changed courses of the cerebral arteries. So, the cerebral arteriograms of normal cases are compared with those of hydrocephalic subjects and the chances of demonstrating the posterior cerebral artery in both groups are analysed. Engeset A. (1948), Saltzman (1959), Yasargil & Krayenbu¨hl (1964) and others reported the demonstration of the posterior cerebral artery but report of a relationship of the artery with hydrocephalus was not found. This study comprises 2,350 conventional carotid angioraphies carried out from 1968 to 1973 in the neurosurgery department of Severance Hospital, Seoul, Korea. Out of these 2,350 angiographies, 1,288 were normal and 160 were indicative of hydrocephalus. The incidencs of angiographic demonstration of the posterior cerebral artery in normal Koreans is 34.2% and in hydrocephalus, 45.6%. This is a higher incidence than is reported in the literature concerning conventional carotid angiography. The number of cases where the posterior communicating artery alone was filled was so small that there was no point in separating them according to age and sex, etc. Generally the hydrocephalic group showed a higher incidence of the posterior cerebral and posterior communicating arteries than the normal group. In all cases, the effect of sex difference is not significant but the effect of age is. The posterior cerebral artery was more visible in the younger groups and occurred most frequently in the youngest group, while the incidence dropped slightly in the higher age groups, in both normal and hydrocephalus groups. Filling of the posterior cerebral arteries in subjects aged 10-30 is markedly more frequent than in the 40-60 age range in both the normal and hydrocephalus groups. The posterior cerebral artery was demonstrated in 148 out of 384 (38.6%) internal carotid arteriograms and in 292 out of 904 (32.3%) common carotid arteriograms. This difference is highly significant and is similar to the results of Saltzman (1959). No significance of the right or left side difference could be found. The increasing tendency of the filling of the posterior cerebral artery in the more severe forms of hydrocephalus compared with the milder types was noted. In this report, the statistical significance was evaluated by means of the z-test.

Empty Sella Syndrome

韓允善,鄭헌和,李憲宰 최신의학사 1972 最新醫學 Vol.15 No.12

Empty Sella Syndrome, first described by Busch in 1951 in cases which the pituitary formed only a thin layer of tissue at the bottom of a sella, is a poorly defined term. Deterioration in visual function after pituitary surgery is usually assumed to indicate recurrence. of tumor. However no tumor is found when enlarged sella is explored surgically on rare occasions. The cause of syndrome is variable from a congenital absence of the diaphargma or widening of the .infundibular outlet, postradiation vasculitis, occlusion of small vessels, vascular strangulation to intrasellar non-neoplastic cyst. We are reporting one. case of this.syndrome encountered recently at Yonsei University Medical Center.

제4뇌실 뇌낭충증

Cerebral cysticercosis has a world-wide distribution, being found frequently in Mexico, parts of Central & South America, Spain, Eastern Europe & the Far East. A few cases have been reported in Korea. The cilnical manifestations are dependent on the intensity of the infestation, number of parasites, their particular locations as well as other toxi-immuno-biologic reaction still poorly known and understood. In the ventricular variety, the lesion may be located within the lateral, 3rd or 4th ventricles as a solitary cysticercosis vesicle or there may be multiple cysticerci. The clinical course in typified by hypertensive crisis followed by spontaneous remisssons caused by transitory and intermittent episodes of cerebrospinal fluid blocking. These patients, are, as a matter of fact, the best candidates for successful immediate surgical treatment. Conray ventriculogram is the most significant diagnostic procedure and it shows definite location and size of the cystic mass. Three cases of cysticercosis in the 4th ventricle are reported and typical ventriculographic findings are briefly discussed.

뇌로 전이된 인세포암(Signet-Ring Cell Carcinoma) 1례 보고

허양옥,이동화,박응범,이유복,정헌화,김헌주,김상철,정상섭,이헌재 中央醫學社 1975 中央醫學 Vol.28 No.4

The metastatic carcinoma of the brain comprises about 15 to 25 per cent of total brain tumors and most of them originate from the lung. Additional primary sites such as the breast, kidney, large intestine, prostate are rare and the stomach as primary site is very rare. We experienced a case of metastatic signet-ring cell carcinoma to the brain originated from the stomach, which was thought as subdural hematoma at the time of admission.
