Tuberculous meningitis, which commonly causes thick granulations over the base of the brain, is a frequent cause of post-meningitic hydrocephalus. Raised intracranial tension affects the cause of tuberculous meningitis adversely. The development of hydrocephalus may account for the raised intracranial pressure. Insertion of a V-A(V-P) shunt significally alters the course of the disease. The results in 5 cases have been detailed and discussed. Operation could be performed even in an active stage of the disease without much fear of milliary dissemination.

A direct intracranial operative approach that occludes the neck of the aneurysmal sac by clipping, and excludes it from the circulation without interference with the lumen of the parent vessel, is the ideal treatment of symptomatic intracranial aneurysm. With this procedure, however, there is no assurance of complete obliteration of the aneurysmal sac. Furthermore aneurysms arising from the anterior communicating artery are particularly dangerous because of the effects produced by spasm of the important neighboring perforating vessels. Since Logue published on the treatment of anterior communicating aneurysms by proximal ligation of an anterior cerebral artery in 1956, there has been by the large number of series of cases reported by other surgeons. Tindall classified three pattern of angiographic filling in patients with anterior communicating aneurysms and in type III, each anterior cerebral artery fills from its respective side, while the aneurysm fills from one side only, proximal ligation of anterior cerebral artery was performed with good effect. Five patients with anterior communicating artery aneurysm were treated by proximal occlusion of the dominant anterior cerebral artery with no mortality or morbidity. There was also instance of recurrent hemorrhage during the follow up period for 8 months to 5 years. We thought this operative procedure, therefore, can offer a highly acceptable result if the surgeon applies strict criteria to patient selection. Technically, the procedure was simple, earlier and could be performed more quickly than the direct attack.

Surgery of the facial nerve may be required for the restoration of function when the nerve is paralyzed from trauma or disease and to reduce or abolish function when the muscle it supplies are involved in severe spasm. A case of facial-hypoglossal anastomosis is reported, in which intracranial injury and destruction of the left facial nerve were resulted from the operation with complete removal of a large acoustic neurinoma in the cerebellopontine angle. The anastomosis was required for innervation of the paralyzed facial musculature following the operation. The anastomosis is preferred to the accessory-facial combination because of the extensive muscular atrophy of the upper trapezius and sternocleidomastoid muscle. Using operating microscpe, the proximal hypoglossal nerve was approximated to the distal facial nerve below the posterior belly of the digastric muscle, and the descendens hypoglossal was anastomosed to the distal hypoglossal nerve to prevent some of the glossal hemiatrophy.

Since Maisonneuve mentioned osteomyelitis by typhoid fever for the first time in 1835, numerous investigators had reported salmonella osteomyelitis. But these are very rare in its incidence ; only 0.82% of patients with typhoid infections have skeletal involvement. The authors recently experienced a case of salmonella osteomyelitis in lumbar spine respectively caused by salmonella typhi D group. A 48 year-old female was admitted to our Dept. of Neurosurgery with 4 months history of severe lumbago. On hospitalization her emperature raised upto 39 degrees C once and widal test showed salmonella typhosa OH 640x. Lumbar spine X-ray films demonstrated irregular bony destruction of L2 and L3 with mild degree of narrowing of intervertebral space of L2-3. Pus evacuation and currettage of involved vertebrae surgically were performed. Salmonella osteomyelitis involving intervertebral space was confirmed by culture of pus obtained from pathologic lesion and by biochemical test. Satisfactory result is obtained by surgical and antibiotic therapy.

A case is presented in which left-sided hemiparesis was caused by a fibromuscular dysplasia of the right internal carotid artery in the neck, and it used as a basis for discussion of the angiographic features. The 24-year-old woman was admitted to our Department of Neurosurgery, Korea University hospital, with the complaints of headache and left-sided hemiparesis which developed abruptly about one month before this admission. The carotid angiography was performed by puncture of the right common carotid artery under the clinical impression of cerebral thrombosis, which showed no gross intracranial abnormalities. But the characteristic findings were observed under and widening of the arterial lumen which are so-called loose stocking appearance or 'string of beads' appearance and are the typical feature of fibromuscular dysplasia. No surgical interventions such as arterial reconstruction and grafting, or arterial dilatation with bougies were applied on the patient, and she was discharged from the hospital three days after the admission. Fibromuscular dysplasia is a rare sclerotic, noninflammatory lesion of unknown etiology involving the wall of large arteries. This disease is found most frequently in early adult life and women are afflicted more often than men, This condition has been described most often in the renal arteries, where it has been found to be a cause of hypertension. Among the involvement of carotid system, the cervical portion of the internal carotid artery is most often affected, and the involvements are often bilateral. When localized to the internal carotid arteries, it can give symptoms of intermittent or permanent cerebral ischemia, but is usually asymptomatic. The typical angiographic appearance is the main parameter for diagnosis of fibromuscular dysplasia.

Acute gastric mucosal lesions (AGM lesions) is a general term applied to conditions characterized by the acute development of mucosal lesions in the form of erythema, mucosal hemorrhage, erosions and ulcerations in the mucosa of the stomach and duodenum. Although the pathopphysiological events leading to the formation of these lesions remain unknown, we do know that they are after preceded by one of many situations. It has become traditional to use the term stress ulcer to describe AGM lesions proceded by a major stress such as that of an operation or of severe thermal burns or hemorrhagic shock. The silent clinical manifestation of acute gastric mucosal lesions, regardless of their cause, is bleeding. AGM lesions were experimentally produced by brain injury and administration of steroid. This experimental study was conducted in order to study the so called AGM lesions, especially on production and pathology of them. This experimental animals, normal adult rate, were divided into 4 groups the first group of brain injury, the second group of brain injury and administration of steroid, the third group of administration of steroid only, and the fourth group of normal control with administration of normal saline and normal rats. The frequency of AGM lesions was studied in relation to each experimental group, experimental period and grade of lesions. The AGM lesions were divided into 3 grades depending on the macroscopic and microscopic findings. 1. AGM lesions were observed in 34 out of 63 all experimental animals except for control group of animal. Majority of the lesions were found in the glandular portion of the stomach. 2. In the brain injured group, the lesions that was erythematous and superficial mucosal erosion were found in 3 out of 21(14.3%), which were observed only in experimental period of 3-5 days. 3. In the group with brain injury and steroid administration, the lesions were found in 16 out of 21 animals(76.2%) among them grade 1 was in 2 out of 16, grade 2 in 10 and grade 3 in 4, which observed in the period of 2-7 days. 4. In the group with administration of steroid, the lesions were found in 15 out of 21 animals(71.4%), among them grade 1 was 2 out of 15, grade 2 in 11 and grade 3 in 2, which started to be observed form 2nd day through out the experimental period. 5. No lesions were investigated in the control group. No correlation between the variety of brain injury and production of AGM lesion was studied.

A teratoma is a true tumor or neoplasm composed of multiple tissue of kinds foreign to the part in which it arises. Predilection site of intracranial teratoma are the pineal body, the pituitary region and the posterior fossa in order of frequency. We have reported a case of teratoma experienced in a boy aged 12 who disclosed various clinical manifestations of right frontal lobe tumor. The teratoma was malignant histologically and located deeply in the white matter of the right posterior frontal lobe.

Trigeminal neurinomas are relatively rare tumors that arise from the sheath of Schwann and constitute 2.9% of intracranial neurinomas and 0.26% of all brain tumors. The most cases are confined to the middle fossa and arising from the Gasserian ganglion. In slight fewer cases the tumor occupy the cerebellopontine angle. In minority it is an hourglass form both situations. By reason of their rarity, the complex clinical problems which may present and the difficult technical aspects involved in their removal, neurinomas of the Gasserian ganglion are of extreme interest. We are reporting a case of trigeminal neurinoma which was arised from the right Gasserian ganglion and located in both situations of middle and posterior cranial fossas. A 37 year-old female was admitted to our department with characteristic symptoms and signs involving many cranial nerves, cerebellum and cerebral peduncle. We chose temporal craniotomy and approached to and exposed the mass by extradural and intradural techniques. Complete removal of the tumor occupying the middle and posterior cranial fossas are accomplished satisfactorily.
