- Laserthermia is a new method of local hyperthermia using fiber optic guided probe with computer controlled Nd-YAG laser system. We used a synthetic sapphire probe and allowed irradiation with contolled low power laser energy (less than 5W), in different thermal condition (temprature:38.5-50 degrees C) for 10 minutes, in the normal brain tissue of 18 rabbits. In results, the histological changes of brain tissue was variable (myelin condensation, chromatin condensation, nuclear waving and palisading, RBC discoloration, cell necrosis) in microscopic findings after laser irradiation, but changing area was not occured proportionally in thermal condition level. Cell necrosis appears to over 44.5 degrees C and the distance was about 1.25 mm. This study, using computer controlled laserthermia system for interstitial local hyperthermia, may offer many advantages in the experimental treatment and clinical management of tumor. Minimizing normal tissue damage is now being developed.

- 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.

Abstract

- 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.

- Nonsurgical management of four cases of the parasagittal epidural hematoma were experienced. Patients were mildly symptomatic or minimal neurological disturbances on admission. Patients were treated conservatively because of stable neurologic sign. All patients had who diastatic fracture and / or suture have become a complete neurological recovery with satisfactory absorption of EDH over a period of 5 to 12 weeks.

Abstract

- Astrocytoma in the thalamus in not so frequent in incidence (1%). Moreover, bilateral thalamic tumor is rare. Certain tumors of the thalamus are considered resectable but most of thalamic tumors are thought to be untouchable. Bilateral thalamic astrocytoma with hydrocephalus was diagnosed by stereotactic biopsy and ventriculoperitoneal shunt operation was done with result of improvement. We report a case of astrocytoma in the bilateral thalamus with literature review.

Abstract

- In an attempt to eliminate some negative aspects of conventional extensive laminectomy, 4 cases of multiple level of cervical compression myelopathy, 1 OPLL (ossification of posterior longitudinal ligament) and 3 cervical stenosis, were treated with a technique of expansive laminoplasty. Operative results in all patients were satisfactory without surgical complications and all patients had a neurological improvement. We suggest that our technique is more effective one for cervical canal stenosis, OPLL, and spondylosis than conventional extensive laminectomy.

Abstract

- The incidence of multiple meningiomas found prior to the introduction of CT was 1~2%, the incidence since the introduction of CT was 8.9%. The authors report a case of multiple meningiomas without evidence of von Recklinghausen's disease. The possible presence of more than 1 tumor in a patient with an intracranial meningiomas must always be kept in mind. The pathogenetic factors related to true multiple meningiomas in unknown. We report a patient with multiple meningiomas which was confirmed by operation.

- Cryptococcosis of central nervous system in uncommon, but fatal if untreated. We experienced a case of cryptococcal ventriculitis with hydrocephalus. The symptom was an increased intracranial pressure without meningeal irritation sign. It was confirmed by pathology and cytology taken from fibrous material, which caused an obstruction of shunt catheter in the lateral ventricle. We report a case of cryptococcal ventriculitis in 6 years old male child.

- The management of pineal region tumor remains controversial. This paper reports a case of pineocytoma which was attempted to improve treatment planning by the use of clinical features, computerized tomography, and markers for germ-cell tumor. A presumptive diagnosis could be made and this tumor less likely to respond to radiotherapy was subjected to primary surgery.

Abstract

- The authors report a case of massive spontaneous intracerebral hematoma in a infant, caused by bleeding from cryptic vascular malformation associated with vitamin K dependant factor deficiency. The bleeding was initiated by vitamin K dependant factor deficiency, then 3 weeks later hematoma was expanded by rebleeding from malformed vessel after PT and PTT had been returned to normal values. The well circumscribed organized old hematoma with fresh expanded bleeding component within a huge rusty colored cystic fluid cavity was recognized in operative field and pathological ground.
