We report a case of cerebral lymphomatoid granulomatosis in a 50-year-old man. Lymphomatoid granulomatosis is an unusual condition which usually presents as a pulmonary manifestation, which occasionally affects the brain, and causes focal inflammatory lesions. Primary cerebral lymphomatoid granulomatosis is very rare. We describe a case of lymphomatoid granulomatosis in the left frontal lobe without pulmonary involvement.

It should be stressed that intracranial tumors in childhood are common. If the leukemia are excluded, intracranial neoplasms are the relatively common type of neoplasms seen in childhood. There are many different kinds of tumor which occur within the cranial cavity. These different tumors grow at different rates of speed and the diversity of location is sufficient so that there is a broad spectrum of different clinical syndromes. However, it is important to recognize the earliest symptoms because of the possibility of operable management and high cure rate on some cases. The author analyzed 58 cases of intracranial neoplasm which were histologically confirmed after operation and autopsy, seen at the Department of Neurosurgery, Jung-Ang University, Sung-Sim Hospital and National Medical Center over the recent several years. These tumors were explored surgically and the diagnosis was made through histological examination. The cases were reviewed as to history, development and progression of the neurological features, laboratory findings, neuroradiological findings, operative methods and pathology. The author emphasized some interesting points and the following were presented here-in as the results. 1) Among 58 cases of intracranial neoplasms in Korean children below 15 years old, the most common tumor was astrocytoma(36%), and the next common tumors were craniopharyngioma(15.5%), ependymoma(12%), and medulloblastoma(10.3%) in that orders. It was interesting that 3 cases of tuberculomas were found in recent three years(1975-1977) and all were located in the cerebellum. A 5 years old boy who was operated for 4 th. Ventricle medulloblastoma confirmed by clinicopathological finding, had another tumor, craniopharyngioma which was found at the postmortem examination. 2) The tumors were occupied on the infratentorial region in 30(5.7%) cases and supratentorial region in 28(48.3%) cases. The most frequent tumor in supratentorial region was craniopharyngioma and in infratentorial region was cerebellar astrocytoma. And the glioma and medulloblatoma were common in turn. 3) Fifty eight cases comprised 36 males and 22 females with a ratio of 1.5 to 1. The age ranged from 5 months old to 15 years old with the peak in the incidence between 5-11 years of age. 4) The main clinical symptoms and signs were headache(84.5%), vomiting(77.6%), papilledema(67.2%), and cranial nerve dysfunction(62%). It was interesting points that neck stiffness(27.6%) and abdominal pain(15.5%) were frequent complaints which should not overlook for the symptoms of simple gastritis or tuberculous meningitis. 5) The results of operative management obtained as follows with excellent in 4, good in 8, fair in 13, and poor in 9 cases. The overall mortality rare was 41% and recurrence rate was 14% during 5 years follow up.

A 46 year-old male with drowsy mentality and left hemiparesis had been treated. Right carotid angiogram showed a mass effect on the posterior temporal region. Preoperative CT brain scan revealed two separated hypodense masses with ring enhancement on the each hemisphere. The right-sided mass was totally removed and there was no invasion into the ventricle and meninges. The histological diagnosis was a glioblastoma multiforme. The left-sided mass was followed with the repeated CT scan, which showed the similar CT findings of a glioblastoma multiforme, and there was no evidence of commiccural extension. The above findings were consistent with the criteria of multicentric tumor.

The author studied the changes of the plasma arginine vasopressin(AVP) levels in 10 brain surgery patient to evaluate the water balance during the postoperative period. The control group was 15 normally hydrated adult subjects. The plasma AVP levels were measured by the radioimmunoassays(RIA). The plasma and urine osmolality was also measured simultaneously using the conventional method. The followings were presented here-in as the results. 1) In control group, the average plasma AVP level was 2.00pg/mL with the range of 0.4 to 5.6pg/mL. There was relative constant relationship between the plasma AVP and the plasma osmolality. The osmotic threshold was 280.4mosm/Kg. 2) In preoperative brain surgery group, the plasma AVP level was similar to control group but the range was wider than control group. There was no constant relationship between the plasma AVP level and the plasma osmolality. 3) The plasma AVP levels were markedly increased in the postoperative brain surgery group. The average level was 10.99pg/mL ranging 0.4 to 47.50pg/mL. In spite of increased plasma AVP concentration, the plasma osmolality and urine/plasma osmolality(Uosm/Posm) ratios were relatively constant to normal control and preoperative brain surgery group. 4) The relationship between the plasma AVP level and the Uosm/Posm ratio was changed according to the plasma AVP level but above 3.0pg/mL it was nearly constant.

We present a series of 10 Patients(Seven men and three women with an average age of 53 years) who underwent decompressive craniectomy for treatment to massive brain swelling following acute cerebral infarction. Clinical signs of cerebral herniation(anisocoria or fixed and dilated pupil, and/or hemiplegia with decerebrate righidity) were present in all patients. Computed tomography and magnetic resonance imaging showed the mass effect by cerebral edema through midline shift. All patients were treated with an extensive craniectomy and duroplasty. Among them, one recovered without neurological deficit, three were moderately disabled but functionally dependent, three remained in a persistent vegetative state and three died within 9 days after surgery(good recovery=1, moderate disability=3, persistent vegetative state=3, death=3). The results suggest that decompressive craniectomy can be an useful lifesaving procedure for massive cerebral edema following widespread hemispheric infarction.

As an attempt to better understand the microanatomy during transpetrosal surgery and to determine the limitation of extradural middle fossa approach, 16 adults human cadaveric skull base speciments were dissected at the region of petroclivus and posterior cavernous sinus. The important landmarks chosen for this study included the following: a petrosigmoid intersection, arcuate eminence, foramen spinosum, foramen ovale, hiatus of greater superficial petrosal nerve (GSPN), porus acousticus internus, geniculate ganglion, cochlea and petrous portion of internal carotid artery(ICA). The resultant data are as follows: the length between the petrosigmoid intersection and the arcuate eminence was 23.1mm+/-1.9(20.1-26.5). The depth covering geniculate ganglion was 1.3mm+/-0.3(0.8-1.8). The length between the geniculate ganglion and the hiatus of GSPN as well as cochlea were 4.6mm+/-1.1(3.5-7.1) and 0.9mm+/-0.2(0.7-1.2) respectively. The whole length of the GSPN exposed the middle cranial fossa was 11.0mm+/-0.8(9.3-12.5). The diameter f the petrous portion of ICA was 5.9mm+/-0.2(5.5-6.4). The length of the horizontal segment of the petrous ICA that can be exposed for anastomosis was 10.8mm+/-0.9(9.0-12.3). The distance between geniculate ganglion and porus acousticus showed a sighificant difference in all measurements to be compared with right and left side(p<0.05). The angle between the internal acoustic meatus and GSPN correlated inversely to the length of horizontal segment of pertrous ICA(r=-0.54, p<0.05). Morphometric analysis and their correlation between bony landmarks and structures within the pyramid helped to decide the angle and direction from which bone removal could be accomplished more safely during transpetrosal surgery, including the middle fossa approach.

Spinal stenosis denoting a critical reduction of the A-P diameter of spinal canal, foramina and lateral recesses can be existed in both cervical and lumbar regions. But it is relatively rare that cervical and lumbar spinal stenosis are coexisted simulataneously. The authors report a case of coexisting cervical and lumbar spinal stenosis with historical background and discussion. The patient was 49 years old male who complained intermittent neurogenic claudication, paraparesis and voiding disturbance. A successful result was obtained through one stage decompressive laminectomies in cervical and lumbar reaions.

A 48 year-old male with back pain and foot drop had been treated. Studies for myelomatosis were all negative. A plain lumbar spin X-ray showed an erosion of the left pedicle of the first lumbar vertebra. A myelography via lumbar and cisternal routes revealed total block with feather appearance at the upper level of the L2 and the lower level of the T12 vertebra. Pathologic evaluation confirmed the diagnosis of solitary myeloma of the bone. After undergoing almost total excision, followed by radiation, the patient was still doing well.

To know recent research works in neurosurgical fields and to analyze neurosurgery related sites on the internet, authors have been searching sites on the web offering the neurosurgical resources. From December 1995 to October 1996 we used a modem(28.8Kbps) and thereafter connected to a LAN(local area network). Under the environment of Windows 95, we used web browsers with Netscape 2.02 and Netterm 2.89. We got an medical information with PC journals or seminars and graded the neurosurgical center/institutes from A to E according to the quality of web sites. We could use the internet resources more rapidly in the early morning than noon or evening. Best sites for neurosurgeon were MedMark(http://www.medmark.bit.co.kr/neurosur.html) and Neurosource (http://www.neurosource.com/). The more comprehensive academic neurosurgical site among all web were the Massachusetts General Hospital(http://neurosurgery.mgh.harvard.edu/) and the University North California (http://sunsite.unc.edu/Neuro/uncns/home.html). In 89 neurosurgical center/institutes, 72 sites(80.9%) couldn't supply sufficient information. In conclusion, there are many webs related to neurosurgery on the internet, but useful sites for neurosurgeon are not common. It is necessary to make an effort to find available sites offering more information in the future.

The authors describe a case of tuberculous abscess of the cerebellum that originating probably from pulmonary lesion. The development of such a lesion indicates a persistence of infection and an immunological breakdown which may party have been due to unsatisfactory chemotherapy and protein malnutrition. Tuberculous brain abscess, an encapsulated collection of pus containing viable tubercle bacilli, is quite rare and it is different from tuberculoma in several points. Only five cases of tuberculous abscess have been fully documented and bacteriologically confirmed. The clinical, laboratory, and histopathological findings of those reported cases and the author's have been discussed.
