Subependymal Giant Cell Astrocytoma in the tuberous Sclerosis.: Jin Han Park, Seong Ho Kim, Dong Ro Han, Jang Ho Bae, Sam Kyu Ko, Oh Lyong Kim, Byung Yon Choi, Soo Ho Cho; Yeungnam Univ J Med. 1994;11(2):221-229. Published online December 31, 1994; DOI: https://doi.org/10.12701/yujm.1994.11.2.221

Abstract PDF: Tuberous sclerosis is reported rarely and is associated with systemic lesions including central nervous system, skin, heart, eye and kidney. Approximately 5-15% of individuals with tuberous sclerosis will develop brain neoplasia, almost invariably subependymal giant-cell astrocytoma (SGCA). We experienced a case of SGCA with tuberous sclerosis operated by the transcallosal approach and report with literature review.

Lumbar synovial cyst associated with retrolis thesis: a case report.: Sang Joon Choi, Sam Kyu Ko, Oh Lyong Kim, Yong Chul Chi, Byung Yearn Choi, Soo Ho Cho; Yeungnam Univ J Med. 1991;8(2):222-226. Published online December 31, 1991; DOI: https://doi.org/10.12701/yujm.1991.8.2.222

Abstract PDF: 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.

Correlation of changes of intracranial pressure and clinical manifestations in spontaneous intracerebral hemorrhage.: Eul Soo Chung, Sam Kyu Ko, Oh Lyong Kim, Yung Chul Chi, Byung Yearn Choi, Soo Ho Cho; Yeungnam Univ J Med. 1991;8(2):35-44. Published online December 31, 1991; DOI: https://doi.org/10.12701/yujm.1991.8.2.35

Abstract PDF: 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.

Clinical Analysis of Chemonucleolysis for Treatment of Lumbar Disc Herniation.: Jowa Hyuk Ihm, Seung Chan Baek, Sam Kyu Ko, Yong Chul Chi, Byung Yeran Choi, Choong Bae Moon, Soo Ho Cho; Yeungnam Univ J Med. 1986;3(1):171-177. Published online December 31, 1986; DOI: https://doi.org/10.12701/yujm.1986.3.1.171

Abstract PDF: During last 48 months, in our department 5 patients with single or multiple herniated lumbar discs have received chemonucleolysis. Forty-one of r51 cases have single level herniation and remaining cases have multiple level. Age distribution were from 19 to 59 years old. Over 4 months (longest case: 18 months) follow up revealed as follows: 40 cases (78%) revealed excellent results: 4 cases (7.8%) received discectomy 3-6 months after chemonucleolysis because of recurred symptoms: no anaphylaxis and no major complications were noted.

The Application and Effect of the Brown-Roberts-Wells Stereotactic System in the Management of Intracranial Lesions.: Choong Bae Moon, Wan Shup Kim, Sam Kyu Ko, Jowa Hyuk Ihm, Seung Chan Baek, Yung Chul Chi, Byung Yearn Choi, Soo Ho Cho; Yeungnam Univ J Med. 1986;3(1):53-62. Published online December 31, 1986; DOI: https://doi.org/10.12701/yujm.1986.3.1.53

Abstract PDF: In the past 10 years, modern technology has made deep seated obscure lesions visible. With development of computer technology and various stereotaxic techniques, many new procedures, refinement of old procedures, and development of new applications are possible. The authors are intended to provide a detailed description of our experience with the Brown-Roberts-Wells (BRW) stereotactic system in the evaluation and management of 90 patients with intracranial lesions, and to provide cases presentation of various inaccessible intracranial lesions.
