Delayed Spinal Cord Injury Following Low Voltage Electrical Accident

Although the prediction of a delayed spinal cord injury after a low voltage electrical accident is difficult, we present a young paraplegic man who had delayed spinal cord injury after a low voltage electrical accident while working. Because the passage of an electric current is variable, the tissues far distant from the point of entry may be damaged, including the spinal cord. Low voltage itself is not a safe.

Surgical Outcome of the Unruptured Intracranial Aneurysm / 대한뇌혈관외과학회지

OBJECT: The surgical management of patients with intracranial aneurysm continues to be controversial, but the best results of treating an aneurysm can be achieved with treating it before it ruptures. The purpose of this study is to evaluate the surgical risk of treating unruptured intracranial aneurysms. METHODS: Between January 2000 to December 2007, 46 unruptured intracranial aneurysms were treated with aneurismal neck clipping. The clinical outcome was retrospectively evaluated according to the Glasgow Outcome Scale about one month after surgery. RESULTS: The patients consisted of 24 females and 22 males. The mean age was 56.6 years (range: 37-80). For the aneurysm location, 27 (58.8%) were at the middle cerebral artery, 10 (21.7%) were at the anterior communicating artery, three (6.5%) were at the posterior communication artery, two (4.3%) were at the internal carotid artery, two (4.3%) were at the anterior choroidal artery, one (2.2%) was at the anterior cerebral artery and one (2.2%) was at the vertebral artery. The size of the aneurysm was below 5mm for 6 patients (13%), 6 to 10mm for 30 patients (65.2%), 11 to 25mm for 9 patients (19.6%) and > or =25mm for 1 patient (2.2%). The clinical outcome was good for 39 patients (84.8%), moderate disability was noted for 5 patients (10.9%) and severe disability was noted for 2 patients (4.3%). CONCLUSION: In this study, the morbidity and mortality rates were favorable compared with those of the previous reports. Our results suggest that aneurysms associated with a ruptured lesion or those larger than 10mm could be considered for treatment. These results will be very helpful to determine whether or not to proceed with surgery.

Extradural Cervical Disc Herniation Causing Sudden Brown-se'quard Syndrome: A Case Report

This is a report on the sudden onset of the Brown-Se`quard Syndrome on a patient following extradural cervical disc herniation. Earlier diagnosis and prompt surgical decompression in the lateral cord syndrome yielded a good outcome.

Desmoplastic Fibroma of the Skull

Desmoplastic fibromas are rare intraosseous bone tumors. They are benign but locally aggressive and frequently found in the long bones and mandible. We report radiographic and histopathologic finding of a case desmoplastic fibroma involving right temporal skull bone. A 53-year-old woman presented at our hospital complaining of continuous right side headaches for a year. Simple skull X-ray film showed 3 x 2.5 cm lytic lesion with mild sclerotic margin on right temporal area. A large craniectomy 1cm lateral to margin was fashioned. The resected mass showed encapsulated mass colored white gray. Histologic diagnosis was compatible with that of a the desmoplastic fibroma. There was no evidence of recurrence during the 15months of follow-up period.

Dorsal Short-Segment Fixation for Unstable Thoracolumbar Junction Fractures

OBJECTIVE: This study is to evaluate the efficacy of dorsal short-segment fixation in unstable thoracolumbar junction fractures. METHODS: The cases of 20 patients who underwent dorsal short-segment fixation were reviewed retrospectively. Clinical outcomes were analysed using Sonntag's pain level, work status, and neurological scale according to the modified Frankel classification. Radiological outcomes were analysed using Mumford's anterior body compression(%), canal compromise ratio, and Cobb's kyphotic angle. RESULTS: At the latest clinical follow-up (average=14.6 months), there were 19 (95.0%) in group I and 1 patient (5.0%) in II in pain level35). The postoperative work status were 17 (85.0%) in group I, 2 patients (10.0%) in II, and 1 patient (5.0%) in V. Surgery brought to improve the neurologic status. In success group (19 cases, 95%), the average canal compromise ratio was reduced from 0.57 (+/-0.07) to 0.05 (+/-0.08) (P<0.05), the average anterior body compression (%) was reduced from 41% (+/-17) to 18% (+/-14) (P<0.05), and the average preoperative kyphotic angle was 20.0 degrees (+/-9.0), and corrected to 5.7 degrees (+/-7.1) postoperatively, and progressed to 7.8 degrees (+/-6.2) at the latest follow-up. There was a case of implantation failure in an elderly osteoporotic patient. CONCLUSION: Although there are limitations in the patient number and follow-up period, the present study favors dorsal short-segment fixation for selective cases in unstable thoracolumbar junction fractures.

Diffuse Large B-cell Lymphoma of the Sacral Nerve Root ; Presenting as a Polyradiculoneuropathy

Primary spinal cord lymphomas are rare, and are either extra-/intradural masses with leptomeningeal infiltration or intramedullary in nature. The authors present a patient with a diffuse large B-cell lymphoma involving the sacral nerve root, extension to extradural space, and the cranial nerve.

Aneurysm of the Posterior Inferior Cerebellar Artery: Clinical Features and Surgical Results

OBJECTIVE: Aneurysms arising from the posterior inferior cerebellar artery(PICA) are uncommon. We review literature on that and surgical results on aneurysmal treatment by choice of surgical approach. METHODS: On the basis of radiologic findings & charts, we review retrospectively the surgical results of 12 cases from Mar 1999 to Dec 2003. RESULTS: The mean age of the 12 patients was 55.8(ranged from 36 to 71) and female was predominant (female: male=8: 4). Locations of PICA aneurysms revealed variously(vertebral artery-PICA junction: 8, lateral medullary segment: 2, PICA-anterior inferior cerebellar artery common trunk: 1, telovelomedullary: 1). Surgical approaches & treatments were attempted in 11 cases and embolization was done in 1 case(Far lateral transcondylar or supracondylar approach & clipping: 9, Far lateral transcondylar or supracondylar approach and trapping: 2, suboccipital approach & clipping: 1). The surgical result were 8 of 12 patients were good outcome, 1 of 12 was severely disabled and 3 of 12 were died. CONCLUSION: First, we choose surgical approach by the laterality of aneurysms and surgical or interventional treatment is attempted as soon as possible. The PICA aneurysm is regarded as having a relatively good surgical outcome without drilling of the posterior arch of the atlas.

Pulmonary Metastasis of Malignant Meningioma

We report a case of 41-year-old male with pulmonary metastasis from a recurrent intracranial malignant meningioma, which had two more recurrence, multiple intracranial metastasis. Pulmonary metastasis was developed five years after resection of primary lesion. The metastatic routes and treatment of pulmonary metastatic malignant meningiomas were described.

Coincidental Arteriovenous Malformation with Pituitary Tumor

Coincidental Arteriovenous malformation with pituitary tumor is very rare. Only two cases previously have been published in the world literature. A 63-year-old man was suffered from sudden loss of vision, vomiting and gait disturbance. Initial magnetic resonance image and cerebral angiography revealed a mass contained hemorrhage on pituitary fossa and arteriovenous malformation on the left frontal lobe. The tumor removed partially via transsphenoidal approach, and then embolization was performed for the arteriovenous malformation. Histological diagnosis of the mass was pituitary adenoma.

Stereotactic Removal of Spontaneous Intracerebral Hematoma Using Hematome and Urokinase

We had tried to perform mechanical aspiration using Hematoma and fibrinolytic drainage with Urokinase for treatment of spontaneous intracerebral hematoma(SICH) in 24 patients. Mean initial volume of SICH was 53.65+/-26.34 ml, mean evacuated amount of SICH after Hematoma procedure was 46.25+/-23.64%, and mean evacuated amount of SICH after fibrinolytic drainage after Urokinase was 74.15+/-20.89%, compared with pre-operative status. We could aspirate more than 50% of hematoma if the Hematoma procedure had been performed within 18 hours after ictus(p=0.0306). The rebleeding rate after Hematoma procedure was 8.3%, and overall mortality rate was 12.5%. There results seem to indicate mechanical aspiration using Hematoma and fibrinolytic drainage with Urokinase might be one of the useful method for treatment of SICH.
