Although cavernous angioma itself is not rare, the epidural spinal localization is uncommon and makes preoperative differential diagnosis difficult. An extraordinary case of a thoracic epidural cavernous angioma in very young age, causing sudden paraplegia is presented. Only 79 cases have been reported in the literatures and among them, this kid was the youngest. A 23-month-old boy was referred to us with a 2-day history of sudden both lower limb weakness. Two days before admission, he got up at morning and was unable to stand and even to move the legs. MRI revealed an epidural mass surrounding spinal cord associated with cord compression at the level of the C5 through T3. Through posterior approach with exposure of C6 to T3 level, the hematomatous mass was removed subtotally due to intraoperative bleeding and its ventral location. After the first operation, the weakness of bilateral lower extremities was improved so as to move gainst the gravity. But the next day, the limb weakness was aggravated as same as preoperative status due to mass effect of new hematoma. The second operation was performed to remove the hematoma and to control the bleeding focus. Several weeks later, the limb weakness was improved and he was able to walk. The literatures about spinal cavernous angioma are reviewed.

Objective : To evaluate the clinical results of gross total resection in the surgical approach to spinal ependymoma. Methods : Between June 1995 and May 2009,13 males and 8 females (mean age 34) diagnosed with intramedullary or extramedullary spinal ependymoma were surgically treated at our centre. The neurological and functional state of each patient were evaluated according to the modified McCormick scale. Results : The average follow-up duration was 54 months (ranging from 12 to 168 months). The locations of the lesions were : thoracic region (4, 19%), lumbar region (7, 34%), cervical region (4, 19%), cervicothoracic region (3, 14%) and conus medullaris (3, 14%). Four patients (19%) had deterioration of neurological function in the early postoperative period. The neurological function of three patients was completely recovered at the 6th postoperative month, while that of another patient was recovered at the 14th month. In the last assessment of neurological function, 20 patients (95%) were assessed as McCormick grade 1. No perioperative complications developed in any of our patients. In one patient's 24-month assessment, tumour recurrence was observed. Re-operation was not performed and the patient was taken under observation. Conclusion : Two determinants of good clinical results after spinal ependymoma surgery are a gross total resection of the tumour and a good neurological condition before the operation. Although neurological deficits in the early postoperative period can develop as a result of gross total tumour resection, significant improvement is observed six months after the operation.
Chordomas are rare central nervous system tumors that are found predominantly in the sacrococcygeal(50%) and basiosphenoidal region(35%). Most of the remainder are related to the vertebral bodies and only 1 to 2% of them are known to occur in the thoracic vertebrae. A 15-year-old girl was admitted because of paraparesis. Three months prior to admission, she underwent a lumbar laminectomy at other hospital for the treatment of herniated lumbar disc but paraparesis became rather aggravated after the operation. At admission, MRI showed a low signal T1WI, high signal T2WI mass compressing the cord at T2 vertebral body. The tumor was subtotally removed via costotransversectomy but as the tumor was proven to be a chordoma, a second stage operation via anterior route was followed. At second operation, T2 corpectomy and T1-T3 plate fixation with autogeneous ileac bone graft was performed. Shortly after the operation, preoperative paraparesis disappeared completely and no evidence of tumor recurrence was noticed both clinically and radiologically for next 2 years. Spine surgery at cervicothoracic junction may be technically demanding due to anatomical complexity and hindering large vessels. The authers reviewed this case with special emphasis on the surgical procedure in this region.
Objective : Dermoid cysts are uncommon in spinal cord tumors, and the phenomenon of their spontaneous rupture into the syrinx cavity is quite rare. We aimed to analyze the imaging characteristics and etiologies, and propose some surgical strategies, for this uncommon phenomenon. Methods : We retrospectively reviewed 14 cases with spinal dermoid cysts that ruptured into the cervical and thoracic syrinx cavity. There were six male and eight female cases, aged 21 to 46 years, who had lipid droplets in the syrinx cavity from C1 to L3. The dermoid cysts were always located at the conus. Based on patients' complaints, clinical manifestations, and imaging results, we adopted tumor excision and/or syrinx cavity aspiration in one stage or multiple stages. Results : Three patients had only a syrinx cavity aspiration surgery due to a history of dermoid cyst excision. Eight patients had dermoid cyst resection and syrinx cavity aspiration in one stage. One patient was operated upon in two stages due to the development of new symptoms at nine months follow-up. Two patients underwent only tumor resection since they did not show similar symptoms or signs caused by the cervicothoracic syrinx. The axial magnetic resonance imaging indicated that the lipid droplets were always not at the center but were eccentric. The clinical effect was satisfactory during the follow-up period in this group. Conclusion : The lipid droplets filled the spinal syrinx cavity, not entirely confined to the central canal. Based on the chief complaints and associated signs, we adopted different surgical strategies and had satisfactory clinical results.
Background: Facial hyperhidrosis patients have as much difficulty in personal relationships as the palmar and axillary hyperhidrosis patients. There have been no appropriate treatment, but recently, satisfactory results have been obtained through sympathetic blockade. Thoracoscopic thoracic sympathectomy for facial hyperhidrosis has been known to resect cervicothoracic (stellate) ganglion, but its inherent complications such as Horner syndrome have made the surgeons hesitant to use this method. We, through our experiences in treating palmar and axillary hyperhidrosis for the past 6 years, believed that T2 sympathicotomy would be enough for facial hyperhidrosis and have experimented and obtained satisfactory results. Material and Method: From June 1997 to May 1998, 38 consecutive patients underwent bilateral thoracoscopic T2 sympathicotomy with 2mm instruments at Seoul National University Hospital. Result: All patients were relieved of excessive sweating in their faces immediately after the operation. Postoperatively, 5 patients (13.2%) required insertion of chest tubes because 3 had incomplete reexpansion of the lung, and 2 had hemothorax from severe adhesion. Other complications related to the surgical procedures, such as Horner's syndrome, and brachial plexus injury, were not detected in any cases. The mean hospital stay was mean 1.7$\pm$0.9 days after surgery. Conclusion: T2 sympathetic ganglion is the appropriate resection site for facial hyperhidrosis, and complications such as Horner syndrome can be prevented by not cutting the stellate ganglion. In addition, it is possible to perform the operation by using a 2 mm thoracoscopic instrument, and may obtain much better results.

Objective : Spontaneous intracranial hypotension is a rarely reported syndrome of spontaneous postural headache associated with low CSF pressure and has rarely been demonstrated radiographically or surgically. But recently, it is being recognized with increasing frequency. The purpose of this study was to characterize clinical and imaging features, etiologic factors, and outcome in the spontaneous intracranial hypotension. Patients and Methods : We reviewed our experience with documented cases of spontaneous intracranial hypotension in 5 consecutive patients with orthostatic headaches from April 1998 to April 1999. Results : The mean age was 41 years(from 35 to 49 years). All patients had postural headaches, which were completely alleviated by recumbency position. Nausea, neck pain, horizontal diplopia, photophobia, and blurred vision were noted in some of the patients. Brain MRI showed diffuse pachymeningeal gadolinium enhancement, subdural collections of fluid, and descent of the brain. The opening pressure from lumbar puncture was $4cmH_2O$ or less in three of five patients whereas the opening pressure was within normal range in two patients. All patients underwent radioisotope cisternography and computerized tomographic myelography. On radioisotope cisternography, CSF leakage was suspected at the level of cervical area(1 patient), upper thoracic area(2 patients), mid-thoracic area(1 patient). Computed tomography myelography revealed extraarachnoid accumulation of contrast media(compatible finding with CSF leakage) at the level of cervical or thoracic area. In all patients, the symptoms resolved in response to supportive measures or epidural blood patch(1 patient). Conclusion : Spontaneous spinal CSF leakage is increasingly recognized as a cause of spinal postural headache. Most CSF leaks are located at the cervicothoracic junction or in the thoracic spine and can be demonstrated by variable diagnostic method. The condition is usually self-limiting and its prognosis is typically good.

This study was conducted to investigate the effects of upper thoracic joint mobilization technique using Kaltenborn-Evjenth concept on the range of cervical and thoracic motion and pain in patients with chronic neck pain. The subjects were divided into a thoracic joint mobilization group(n=7) and a conservative physical therapy group(n=7). Each of the groups received thoracic joint mobilization or conservative physical therapy three times a week lasted for four weeks. The measurements were performed for the range of thoracic segmental motion(SpinalMouse), the pain(visual analogue scale) and the range of cervical joint motion(Inclinometer, Dualer IQ). They were made four times: before experiment, at 2weeks, 4weeks, and 4weeks after experiment.

Objectives : The purpose of this study was to evaluate surgical outcomes and complications of spinal deformity associated with neurofibromatosis type-1 (NF-1). Methods : From 2012 to 2018, patients suffering from spinal deformity associated with NF-1 who underwent surgical correction were identified. Demographic data and radiographic measures were retrospectively reviewed. Pre- and postoperative whole spine radiograph images were used to determine both coronal and sagittal Cobb angles. All of patients underwent 3-dimentional computed tomographic scan and magnetic resonance imaging scan to confirm dystrophic features. For evaluation of clinical outcomes, we surveyed the pre- and postoperative scoliosis research society-22r (SRS-22r) score. Results : Seven patients with spinal deformity associated with NF-1 were enrolled in this study. The mean age of patients was 29.5±1.2 years old. The mean follow-up period was 2.8±1.4 years. The apex of the deformity was located in cervicothoracic (n=1), thoracic (n=4), and lumbar region (n=2). Most patients have poor bone quality and decreased bone mineral density with average T-score of -3.5±1.0. All patients underwent surgical correction via posterior approach. The pre- and postoperative mean coronal and sagittal Cobb angle was 61.6±22.6° and 34.6±38.1°, 56.8±18.5° and 40.2±9.1°, respectively. Mean correction rate of coronal and sagittal angle was 44.7% and 23.1%. Ultimate follow-up SRS-22r score (average score, 3.9±0.4) improved comparing to preoperative score (average score, 3.3±0.9). Only one patient received revision surgery due to rod fracture. No serious complication occurred, such as neurological deficit, and viscerovascular injury. Conclusion : The surgical correction of patients having spinal deformity associated with NF-1 is challenging, however the radiographic and clinical outcomes are satisfactory. The all posterior approach can be a safe and effective surgical option for patients having dystrophic curves associated with NF-1.
Background: Descending necrotizing mediastinitis(DNM) is a serious complication originating in odontogenic or oropharyngeal infection with previously reported mortality rates of 25% to 40%. We retrospectively reviewed the 4 years of our surgical drainage and debridement in DNM. Material and Method: We studied 7 cases diagnosed as DNM from 1997 through 2000. Primary oropharyngeal infection lead to DNM in four cases(57%) and odontogenic abscess in three cases(43%). All patients were received emergent cervicotomy and thoracotomy or sternotomy for debridement of necrotic tissue and mediastinal or pleural drainage. Result: Five cases were evolved well and were discharged after a mean of 42 days. Two patients(28.6%) died. Three patients required reoperation due to local surgical complication; empyema(two) and impending cardiac tamponade. One of these patients died on 12 post-reoperative day due to great vessel erosion, renal and respiratory insufficiency. The other patient died of broncho- esophageal fistula and asphyxia on 10 postoperative day without reoperation. Conclusion: On the basis of experience accrued in treating these patients, early diagnosis by cervicothoracic computed tomographic scan of neck and thorax aids in rapid indication of a surgical approach of DNM. We emphasize that performing early surgical drainage and debridement of necrotic tissues with intensive postoperative care can significantly reduce the mortality rate.

Background: Mediastinal neurogenic tumors are generally benign lesions and they are ideal candidates for performing resection via video-assisted thoracoscopic surgery (VATS). However, benign neurogenic tumors at the thoracic apex present technical problems for the surgeon because of the limited exposure of the neurovascular structures, and the optimal way to surgically access these tumors is still a matter of debate. This study aims to clarify the feasibility and safety of the VATS approach for performing surgical resection of benign apical neurogenic tumors (ANT). Material and Method: From January 1996 to September 2008, 31 patients with benign ANT (15 males/16 females, mean age: 45 years, range: 8~73), were operated on by various surgical methods: 14 VATS, 10 lateral thoracotomies, 6 cervical or cervicothoracic incisions and 1 median sternotomy. 3 patients had associated von Recklinhausen's disease. The perioperative variables and complications were retrospectively reviewed according to the surgical approaches, and the surgical results of VATS were compared with those of the other invasive surgeries. Result: In the VATS group, the histologic diagnosis was schwannoma in 9 cases, neurofibroma in 4 cases and ganglioneuroma in 1 case, and the median tumor size was 4.3 cm (range: 1.2~7.0 cm). The operation time, amount of chest tube drainage and the postoperative stay in the VATS group were significantly less than that in the other invasive surgical group (p<0.05). No conversion thoracotomy was required. There were 2 cases of Hornor's syndrome and 2 brachial plexus neuropathies in the VATS group; there was 1 case of Honor's syndrome, 1 brachial plexus neuropathy, 1 vocal cord palsy and 2 non-neurologic complications in the invasive surgical group, and all the complications developed postoperatively. The operative method was an independent predictor for postoperative neuropathies in the VATS group (that is, non-enucleation of the tumor) (p=0.029). Conclusion: The VATS approach for treating benign ANT is a less invasive, safe and feasible method. Enucleation of the tumor during the VATS procedure may be an important technique to decrease the postoperative neurological complications.
