The incidence of spinal meningioma is very rare in children. A 14-year-old girl presented with right arm weakness, gait disturbance, and urinary incontinence. Cervical magnetic resonance imaging revealed an intradural extramedullary tumor dorsal to the spinal cord in the level of C1. The tumor was totally removed despite the severe cord compression. Meningotheliomatous meningioma was diagnosed after histological examination.

We report a case of anterior spinal epidural hematoma, after removal of cervical meningioma by posterior approach, which occurred in a 61-year-old man who presented with left hemiparesis and hypalgesia. A cervical mass surgically confirmed as meningioma was removed by posterior approach. 3 hours after operation, the patient revealed quadriparesis with respiratory difficulty. We herewith report a rare case of anterior spinal epidural hematoma which caused a catastrophic aggrevation of postoperative course.

Spinal meningiomas located purely in the extradural space are rare, and they may easily be confused with malignant neoplasm. We report an unusual case of a purely extradural spinal meningioma mimcking metestatic neoplasm. A 38-year-old woman had neck pain and left side weakness. MRI scan revealed extradural spinal mass. Preoperative and intraoperative diagnosis was metastatic carcinoma, but permanent diagnosis was extradural meningioma.

The authors report a case of 42-year-old woman with an intraventricular tumor in the trigone of the left lateral ventricle. The first operation achieved a microscopically complete resection. The tumor was histologically atypical meningioma. After 26 months, there were recurrences of intraventricular meningioma. Complete resection of the tumor and adjuvant radiation therapy were performed, and the histological diagnosis was malignant meningioma. Sixteen months after the second operation, spinal metastasis in cervicolumbar lesion was diagnosed and a subtotal removal of cervical intradural extramedullary mass was performed. We describe an unusual case of intraventricular malignant meningioma with cerebrospinal fluid-disseminated spinal metastases with review of the clinical courses of previous reports.

The meningiomas are slowly growing tumors arising from meningoepithelial cells and they generally occur in the intracranial space. Tumor extension to the extracranial structures occurred in about 20 percent of intracranial meningiomas. Meningiomas extending to the cervical area are uncommom. Beacuse these patients complain of localized symptoms, sometimes those tumors have been operated as cervical tumors. In this report, we incidentally found a meningioma in the left parapharyngeal space in a 63-year-old female, who was confirmed by histopathologic diagnosis to have meningioma. We report herewith this case with the review of literatures.

Objective : The authors reviewed 51 patients of spinal cord tumor located at the craniovertebral junction and high cervical area to determine which factors influenced resectability, complications, and postoperative outcomes. Methods : Radiological examinations, clinical data, and operation notes were evaluated, and additional follow-up information was obtained from outpatient examinations. The mean follow-up period was 3.5 years Results : The most common neurological findings were motor deficit(72.5%) and sensory change(47.1%). There was no clinical finding that is considered as pathognomic. Meningioma(18 cases, 35.3%) was the most common tumor in this region. Total removal was achieved in 45 patients. There was no surgical mortality. Immediate postoperative motor weakness were encounted in 11 cases(21.6%) which improved in long term followup except two patients. Conclusions : The location and relationship of the tumor to surrounding struncture determine its resectability. Postoperative results were related to the preoperative neurological status and pathological findings.

체중 2.7 kg의 5세령 암컷 말티즈 견이 양측 슬개골 탈구와 후지 파행으로 지역동물병원에 내원하였다. 도르레절제술과 슬개골의 외측 보강 봉합법을 이용하여 슬개골 탈구 정복술을 실시하였으나, 수술 3주 후 등을 굽힌 자세의 보행과 후지의 운동실조, 흉요추부의 압통, 간헐적인 경련증상으로 재 내원하였다. 자기공명영상 촬영 결과, 우측 전두엽의 종괴와 경수에서부터 3번 요수까지의 공동성 변화가 확인되었다. 병리조직학적 소견으로 뇌종양은 느슨한 망상구조 또는 레이스 모양의 수막세포들로 구성되었으며, 세포 외부에 다양한 크기와 형태의 많은 낭포성 공간이 관찰되었다. 면역조직화학염색 결과 종양세포들은 vimentin 양성, 신경원 특이 에놀라제 및 신경교 섬유질 산성 단백질에는 음성을 나타내었다. 경수와 흉수 부위에는 부정형의 확장된 중심관 유사 동공이 관찰되었다. 이 증례는 개에서 특이적인 두개강 내 소낭성 뇌수막종과 연관되어 2차적으로 발생한 척수공동증의 임상소견과 영상학적 및 병리조직학적 특징을 보여주고 있다.

Background: An increasing number of traumatic, infectious, degenerative, benign, and malignant lesions of the clivus and cervical spine are treated by head and neck surgeons. Surgical techniques vary according to the exact level of the lesion. Objectives: The purpose of this article are to introduce the surgical approach and to discript our experience and to analyze the advantage of the each methods. Materials and Methods: Transpalatal approach in clivus chordoma, transoral approach in C2 fibrous dysplasia, trans mandibular approach in clivus meningioma and transcervical approach in neulilemmoma were reviewed from the medical record. Results: Postoperative complications occured. Otitis media with effusion were observed in transoral and trans mandibular approach. Cranial nerve paralysis was observed in transcervical approach. But other complications such as swallowing difficulty persisting over 6 weeks, malunion of mandible, orocutaneous fistula, hemorrhage from major vessel were not observed. Conclusion: The various surgical techniques to be described herein serve to give the best exposure of each level of the lesions. Therefore head and neck surgeon plays a major role in the treatment of lesion in the clivus and anterior cervical spine according to the lower incidence of postoperative morbidity.

Rosai-Dorfman Disease (이하 RDD)는 드문 조직구 증식성 질환이며 두개 내에만 발생하는 경우는 매우 드물다. 대부분의 두개 내 RDD는 균질한 조영증강을 동반하는 경막의 종괴들로 나타나서, 심한 경부 림프절증을 보이지 않는 경우에는 수술하기 전에 뇌수막종과의 감별이 어렵다. 저자들은 65세 남자 환자의 두개 내에만 발생한 RDD의 드문 증례에 대해 보고하고자 한다. 뇌 MRI에서 우측 전엽 원개에 경계가 분명한 조영증강되는 종괴의 형태로 보였으며 미세한 확산제한이 관찰되었다. 하지만 수술 전 뇌혈관조영상에서는 겨우 미세한 홍조만이 보였다. 비록 두개 내에만 발생한 RDD가 드물기는 하지만, 경막에 기반한 종괴가 뇌혈관조영상에서 저혈관성의 형태로만 보일 때 감별질환으로 생각할 수 있다.

Total laminectomy for the removal of intradural-extramedullary spinal cord tumors has been used widely, but postoperative complications often develop, such as kyphosis, spinal instability, and persistent back pain. In this study, we evaluated seven patients with intradural-extramedullary spinal cord tumors with respect to the value of unilateral limited laminectomy. Our cases included six schwannomas, and one meningioma. The cervical region was involved in four cases, the thoracolumbar region in two cases, and the lumbar region in one case. The rationale for choosing a unilateral approach is to preserve musculoligamentous attachments and posterior bony elements as much as possible. The patients were mobilized on the third postoperative day and preoperative neurological symptoms were recovered within a few weeks. We did not observe any complication relating to unilateral limited laminectomy and at follow-up evaluation (at 3 and 12 months postoperatively), none of the patients showed spinal deformity or spinal instability. We think that the unilateral limited laminectomy is a safe and efficient technique for the treatment of intradural-extramedullary spinal cord tumors. We suggest that this technique is one of the best treatments for these tumors.
