The eight patients of neurocysticercosis have been diagnosed from 1985 to 1987 in the department of neurosurgery at The Baptist Hospital. Six patients had parenchymal cysts, one had a racemose cyst and the other one had a mixed cyst. The blood serum and CSF ELISA on six patients had a positive reaction for cysticercosis but the follow-up ELISA titers were variable three months later on these four. The racemose and mixed cysts were removed surgically due to mass effect and followed by praziquantel therapy. The parenchymal cysts were treated with praziquantel only. Praziquantel was given daily at 50mg/kg of body weight for two weeks or 30mg/kg of body weight for three weeks. The common side effects of praziquantel were headache, dizziness, nausea, seizure and focal neurological deficits. These side effects could be prevented or minimized by corticosteroid. The result of praziquantel therapy was excellent in all the patients except the mixed cyst.

The report of basilar bifurcation aneurysm accompanying carotid-ophthalmic aneurysm is extremely rare and some technical dexterity must be needed on surgical treatment for each of two aneurysms. Authors report a case of basilar top aneurysm accompanied with a carotid- ophthalmic aneurysm clipped successfully in one stage operation with review of literatures concerning basilar bifurcation aneurysm, carotid-ophthalmic aneurysm and multiple aneurysms.

Aneurysms arising from the posterior circulation are 5-19% of total intracranial aneurysms. Althought many neurosurgeons have challended with various innovations but the confinned surgical space, complicated anatomical structure and many small perforators to vital organ of brain were remained the barrier that we we have to overcome. From July 1987 to December 1994, we have been operated on 23 cases of posterior circuation aneurysms among 409 cases of surgically treated all intracranial aneurysms. The present 5.6% of all intracranial aneurysms, the average age of these patients was 49 years old. The ratio of male to female was 1 : 1.8. The number of basilar bifurcation artery aneurysms(BBAA) were 14(61%), the posterior cerebral artery(PCA) aneurysms 3(13%), the upper basilar trunk aneurysm 1, posterior inferior cerebellar artery(PICA) aneurysm 3(13%), anterior inferior cerebellar artery(AICA) aneurysm 1 and vertebral artery aneurysm 1. Five patients had accompanined with anterior circulation aneurysm and one patient had concomitant arteriovenous malformation. We have successfully clipped 12 cases and wrapped 2 cases of BBAA aneurysms through modified pterional approach and subtemporal approach according to the hight of basilar bifurcation and the other posterior circulation aneurysms are all clipped through most available approaches including lateral, far-lateral suboccipital and interhemispheric approach. Surgical outcome was good in 15 cases, fair in 4 cases, poor in 3 cases and one patient expired.

GDC embolization has been performed selectively since 1991 in patients with intracranial aneurysms and made remarkable technical and clinical advances in recent years. But until now, this procedure lacks an adequate long-term follow-up study. Also, clear mechanism and evidence of electrothrombosis and endothelialization of aneurysm neck, the incidence of vasospasm after GDC embolization are still controversial. Here we critically reviewed the published literatures pertaining to the GDC embolization in order to gain a comprehensive understanding and knowledge of forementioned controversies. Also from November 1997 to April 1999, we treated 12 patients of intracranial aneurysms with GDC embolization. In conclusion, although certain shortcomings and controversies are still remain, the GDC embolization can be an alternative, supportive and attractive therapeutic modality in the treatment of intracranial aneurysms. Not only to improve outcome of intracranial aneurysms but also fulfill the patient's requirement, we need cooperations and cross-training with the interventional neuroradiology and rigorous academic evaluation on anatomy of cerebral vasculature and pathophysiology of cerebrovascular disorders.

The immune system contributes to body defence mechanism, but sometimes show unfavorable immune disease. Cerebral vasospasm is a major problem in aneurysmal subarachnoid hemorrhage(SAH), but the pathogenesis is poorly understood. Some authors suggest cerebral vasospasm is one type of autoimmune vasculitis. In 35 patients(male 20, female 15) with aneurysmal SAH. the levels of serum immunoglobulin(Ig) G, A, M, E and complement C3(C3) were determined to analyze the relation among Igs, C3, cerebral vasospasm and clinical grade. The results were as follows : 1) Highly significant correlation presented between C3 level and cerebral vasospasm(p<0.001). 2) Highly significant correlation presented between IgA level and cerebral vasospasm(p<0.001). 3) Significant correlation showed IgA with admission grade(p<0.001) and outcome(p<0.01). 4) Significant correlation showed C3 with admission grade(p<0.05) and outcome(p<0.01). 5) Among the 4 groups(SAH without vasospasm, SAH within vasospasm, hypertensive intracranial hematoma(HICH), herniated intervertebral disc(HIVD)), significant statistical difference at the level of IgA and C3 with others is observed in the group 2. 6) In serial determination of C3 levels performed in 8 patients(group 1 and group 2), correlative alteration between C3 level and cerebral vasospasm was observed. From the above results, these findings suggest that IgA and C3 levels not only might be reflected the severity of the neurological insult but also provide the usefulness as a predictable marker of cerebral vasospasm in aneurysmal SAH.

The authors presented 36 cases of chronic subdural hematoma which were diagnosed by operation from Fed. 1984 to Aug. 1986 at the Dept. of Neurosurgery, Wallace Memorial Baptist Hospital. The results were summarized as the followings : 1) Males were more frequently involved than female with the ratio of 3.5 : 1, common incidence of age was between 6th decade and 7th decade. 2) Most of the cases(88.9%) had a history of craniocerebral injury and some of them had an alcoholism(38.9%). 3) Older age(more than 50 years) group had more frequent mental changes(80%), and focal neurological deficit such as headache(62.5%) and vomiting(62.5%). 4) The hematoma density of CT scan showed isodense(38.9%), mixed dense(33.3%), hypodense(16.7%), or hyperdense(11.1%) lesion, that was not correlated with duration after head trauma. 5) The hematoma shale of CT scan showed biconvex shape(80%) in older age group that did not show the relation between hematoma shape and the duration of hematoma age. 6) Of the 36 cases, 24 cases were treated with burr hole drainage and intermittent valsalva maneuver, 12 cases with craniotomy and membranectomy, but the operative method did not affect the postoperative results. 7) The analysis and pathological review of hematoma blood and membrane showed the possible role of bleeding from outer membrane to hematoma expansion.

The reports of epidural vascular tumors are rare however dumbbell-shaped epidural cavernous hemangioma is exceedingly rare. The reported incidence of epidural hemangiom is 4%of all spinal epidural tumors and 12% of all intraspinal hemangioma. In the majority of cases, hemangiomas of spinal epidural space represent the secondary extension of a vertebral hemangioma but the occurance of pure epidural cavernous hemangioma is relatively rare. In this report, authors present two cases of epidural cavernous hemangioma including one dembbell-shaped in the thoracic spine with review of other reports.

We retrospectively reviewed 100 consecutive patients who were ruptured intracranial aneurysm and were operated on in the department of neurosurgery of Wallace Memorial Baptist Hospital from August 1984 to August 1988. The patients who were operated upon within the first 3 days of their most recent subarachnoid hemorrhage formed the early group, the patients operated upon with 4-7 days formed the intermediate group, after 8 days were considered as the delayed group. Early operation was performed in 30 patients, intermediate operation in 20 patients, and delayed operation in 50 patients. On the base of their clinical outcome, the patients were allocated to one of 4 outcome categories(good, fair, poor, death) at the time of their hospital discharge. The 80% favorable outcome estimated from early operation and 85% from intermediate operation and 90% from delayed operation. The mortality was estimated 13% from early operation and 0% from intermediate operation and 8% from the delayed operation. Each 4 cases of early, intermediate and delayed operation was needed shunt operation for hydrocephalus. In operative result, after 1987 was better than before 1987. In hypertensive patients, there was a tendency to observe poor prognosis than normotensive patients, especially with vasospasm.
