Compared to the lumbar region, it is very rare to encounter far lateral disc herniation in the cervical spine, and because of this, correct diagnosis before surgery is difficult: the condition can, however, be identified through the use of advanced MRI imaging techniques. In this case, far lateral disc herniation at C7-T1 was effectivery removed through posterior laminoforaminotomy, and soon after surgery, the patient's symptoms showed complete remission.

Recently, many authors have reported about the relationship of the volumes of hemorrhage in the brain parenchyma, hemorrhagic sites, optimal operation time, and the effects of mannitol and steroid on control of ICP to clinical manifestations. Many attempts to measure ICP in hydrocephalus, brain tumor, and head injury have been reported. But the measurements of intracranial pressure in spontaneous intracerebral hemorrhage are rare. Intracranial pressure was monitored prospectively in 30 patients who had stereotaxic surgery for spontaneous intracerebral hemorrhage. The results are as follows. 1. Intracranial pressure was increased in high PaCO₂. 2. There were no correlation in ICP, rebleeding and ADL ad discharge (P>0.05). 3. ICP was the most high level in 72 hours after operation. 4. There was 63.2% decrease in ICP after irrigation with 6000 IU urokinase in the site of hemorrhage. 5. There was no correlation between the numbers of natural drainage and ADL at discharge (P>0.05). 6. The higher the initial GCS, the higher the postoperative GCS.

In advent of high-resolutional CT and MRI, it is not so difficult to detect the lumbar synovial cyst, however the unusual disease should be included in the differential diagnosis of cauda equine compression syndromes. The case of a 55-year-old man who had a low back pain and severe radiating pain on both legs showed a retrolisthesis at L3-4 and L4-5 and epidural enhancing mass just around L4-5 facet joint on MRI. Microscopically a lining of synovial tissue was demonstrated. After surgery of the total resection of synovial cyst and stabilization, the patient's presenting symptoms were improved.

Combining the stereotactic precise localization with open craniotomy can decrease post-operative morbidity and is helpful for total removal of small intra-axial lesion. The authors had good results by the stereotactic guided craniotomy. The method and results of the technique are discussed in reference to 8 patients.

Clinical and cerebral angiographic findings were reviews retrospectively in thirty-seven patients with intracranial artero-venous malformation(AVM). The results were as follow. Many opatients who were in reproductive age had visited due to seiure(27%) and its angiographic findings were mixed Type(80%). Bleeding was predominant in the patients who had small sized nidus than medium or large one, and deep draining vein than superficial one. Medium sized AVM was located mainly in the anatomically deep portion(71%) and drained to deep portion also(71%). Associated aneurysm was more prevalent in deep seated or large sized AVM. Low grade AVM according to Spetzler's grading system showed good results of treatment. Postoperative hemorrhage or sizure were frequently found in patients who had superfically located AVM.

The cranium can be thought of a as shallow, rigid sphere of contrast volume. There are three main components within the intracranial space : brain, cerebrospinal fluid and blood. Intracranial volume and pressure are maintained constantly by Monroe-Kellie doctrine. Also intracranial pressure is influenced by a number of physiologic factors and it will be changed with intracranial lesion. Now we were look for the possible factors that influence the intracranial pressure with continuous intracranial pressure monitoring. At the same time we studied the possibility of the relationship between factors that influence ICP and ADL(Ability of Daily Life) in 43 severe brain lesions(33 cases ; intracerebral hematoma, 10 cases ; head injury). In cases of higher GCS, smaller hematoma, lower amplitude of ICP, lesser frequency of A-wave and lower elastance, the ICP were lowed. Ninety percent of cases that GCS is over 12 was belong to ADL I and II, but only nineteen percent of cases that GCS is under 7 was belong to ADL I and II. No case of internal capsule involved group was belong to ADL I but forty-eight percent of cases whose hematoma volume is under 10ml was belong to ADL I. Fifty percent of cases whose hematoma volume is under 10ml was belong to ADL I and no case that hematoma volume is over 20ml was belong to ADL I. Cases that PCO2 is in the range of 25mmHg-29mmHg were not belong to ADL I. In cases of higher amplitude of ICP, higher frequency of A-wave and higher elastance, the patient's ADL was grave. And in cases of ICP was progressively increased, the prognosis was also grave. Consequently we are able to guess that patient's prognosis will be influenced by initial GCS, internal capsule involvement, hematoma volume, PCO2, amplitude of ICP, frequency of A-Wave, brain elastance and curve of ICP.

Brain Computerized Tomography(CT) and cerebral angiography were reviewed in thirty-six patients with multiple intracranial aneurysms(22.5%) among the 160 consecutive surgical cases of intracranial aneurysms. The prevalent sites of multiple aneurysms were the middle cerebral artery(37.0%), posterior communicating artery(22.2%), and internal carotid artery(14.8%) in sequence. However, the vertebrobasilar system(83.3%), anterior communicating artery(63.6%), and posterior communicating artery(50.0%) had higher probability of rupture than internal carotid artery(8.3%) or middle cerebral artery(33.3%). Based on CT and angiographic information, the site of rupture can be predicted with a high degree of reliability. These factors were the presence of localized hemorrhage on CT, focal vasospasm, size and irregularity of aneurysms, and relative hyperplasia of parent artery.

The authors have been performed stereotactic endoscopy to diagnose and treat 6 cases of ventricular and juxtaventricular lesions using Brown-Wells system under the local anesthesua. We thought that stereotactic endoscopy was easier and safer than conventional surgery for these lesions.

Sixty five patients of lumbar spondylolisthesis were treated with pedicle screw fixation during last 3-years. Roy-Camille plate system has been used in 17 patients, steffee system in 41 and Puno/Winter/Byrd(PWB) system in 7. We analysed the changes of symptoms and radiological findings during follow-up observation(average 15 months). After surgery the average time for low back pain reduction was 7 months, Twenty patients(3%) complained a graft donor site pain initially, but almost except one were alleviated after 7.3 months later on an average. Radiologically the reducton degree of the displacement was from 24% on preoperative state to 12% on last follow-up and pseudoarthrosis rate was 8%. Surgical result was evaluated by our score rating system, according to that system 64.5% of the patients had satisfactory result.

Craniopharyngioma is one of the most challenging, Frustrating, and humbling benign intracranial tumors of childhood. Its behavior is a clinical malignancy even though it is benign tumor in microscopically. There is no single treatment of craniopharyngioma and there must be a plan customized for eacg patient. This decision may, be made from diagnostic studies alone, but in most cases exploration of the tumor and the testing of its adherence to its surroundings will be the only thorough and fair way to determine whether it can be totally excised or not. So the choice of treatment is "individualize". We experienced one case of giant cystic craniopharyngioma and performed combined operaion whih were percutaneous intermittent drainage of cystic fluid through Ommaya reservoir and following microsurgical radial excision. There was no complication and marked intellectual and psychological improvement until todays for 20 months.
