1/1288. Increased intracranial pressure associated with spinal cord tumours.Two cases of spinal cord tumour associated with increased intracranial pressure are reported and the 44 cases described in the literature are reviewed. The different hypotheses produced to explain the pathogenic mechanism of this syndrome are discussed. We think that several factors working together, rather than an isolated mechanism, take part in the production of this syndrome.- - - - - - - - - - ranking = 1keywords = spinal, spina (Clic here for more details about this article) |
2/1288. Anterior approach to intramedullary hemangioblastoma: case report.OBJECTIVE AND IMPORTANCE: Intramedullary spinal cord tumors are generally operated on by using the posterior approach. However, the posterior approach may not be suitable for a tumor in the anterior part of the spinal cord. In this report, we describe a case of a cervical intramedullary tumor that was successfully removed by using the anterior approach. CLINICAL PRESENTATION: A 48-year-old woman presented with lower cranial nerve disturbance and motor weakness of the upper extremities. magnetic resonance imaging revealed a large extensive syrinx and an intramedullary enhanced tumor at the C6 level. The tumor was located at the left of the anterior part of the spinal cord. INTERVENTION: Based on these findings, the anterior approach was used in performing a corpectomy of C5 and C6. The tumor was highly vascular and was resected without resulting in any operative deficits. The pathological diagnosis was hemangioblastoma. CONCLUSION: The present case suggests that the anterior approach is an important option among surgical approaches to the intramedullary tumor in cases in which the tumors are small in size and are located in the anterior part of the cervical cord.- - - - - - - - - - ranking = 0.6keywords = spinal, spina (Clic here for more details about this article) |
3/1288. A case of laryngeal neurinoma with neurofibromatosis 2.We present a case of a laryngeal neurinoma in a patient with neurofibromatosis 2. A 39-year-old man presented to our hospital with multiple complaints including progressive bilateral hearing loss, dizziness, dyspnea, dysphagia, and a 9-year history of right lower leg weakness. magnetic resonance imaging demonstrated multiple lesions including bilateral cerebellopontine angle tumors, a foremen magnum tumor, multiple tumors of the spinal cord, a laryngeal tumor, and several retrocervical tumors. Fiberoptic laryngoscopy revealed a large submucosal supraglottic tumor. The laryngeal tumor was visualized through microlaryngoscopy and excised with a KTP laser directed through a quartz fiber.- - - - - - - - - - ranking = 0.2keywords = spinal, spina (Clic here for more details about this article) |
4/1288. Extraneural metastasizing ependymoma of the spinal cord.This paper reports a case of the rare entity of an extraneural metastasizing ependymoma of the spinal cord. The tumor which arose in the conus medullaris and in the cauda equina was first diagnosed in 1956 when a thoracolumbar myeloresection was performed. At autopsy, 40 years after the primary diagnosis, a massive local tumor recurrence with extraneural metastases in the lungs, the pleura, the liver, and the thoracal and abdominal lymph nodes were found. Immunohistochemical stains of the extraneural metastases showed a strong cytoplasmatic expression of glial fibrillary acidic protein (GFAP). Neither the primary tumor nor its metastases showed any of the conventional morphological criteria of malignancy. Reviewing the literature we discuss the possible mechanism of extraneural tumor spread and the incidence of metastases with regard to the tumor type.- - - - - - - - - - ranking = 1keywords = spinal, spina (Clic here for more details about this article) |
5/1288. dermoid cyst with dermal sinus tract complicated with spinal subdural abscess.Spinal subdural abscess caused by spread of infection with the dermal sinus tract is rare in children. This article reports on a 1-year-old male with prolonged fever, progressive paraplegia, and bowel and bladder dysfunction resulting from a spinal subdural abscess secondary to an infected spinal dermoid cyst with a dermal sinus tract. This is the youngest patient to be reported having this condition. Surgical intervention was performed to find a tumor that had capsule and keratinlike contents. culture of the abscess was positive for escherichia coli and bacteroides vulgatus. He received 6 weeks of parenteral antibiotic treatment. This patient illustrates the importance of urgent radiologic examination, immediate surgical resection, and appropriate antibiotic therapy for spinal subdural abscess.- - - - - - - - - - ranking = 1.4310536400803keywords = spinal, dermal sinus, spina, sinus (Clic here for more details about this article) |
6/1288. Primary melanocytoma arising from the thoracic leptomeninges case.Primary melanocytoma arising from the leptomeninges of the spinal cord is very rare. A surgical specimen of a thoracic meningeal tumor was resected from a 75-year-old woman complaining of gait disturbance was investigated. magnetic resonance imaging and myelography showed a dumb-bell-type tumor in the subdural space at the 1st to 2nd thoracic vertebrae. The tumor was subtotally resected because of adhesion to the lamina and thoracic medulla. The localized, gelatinous black tumor showed a well-defined margin without dissemination or infiltration. The tumor had a thin capsule and was composed of solid proliferation of neoplastic melanocytes. Neither whorl formation nor foci of palisaded nuclei were observed. The neoplastic cells were of two major types: an epithelioid- or polygonal-shaped type and a spindle-shaped type, and had a large nucleus, a prominent nucleolus, coarse chromatin, and melanin-pigments in their cytoplasm. Only a few mitotic figures were observed. They were positive for HMB-45 and S-100 protein. This case was considered to be primary melanocytoma arising from the thoracic leptomeninges.- - - - - - - - - - ranking = 0.2keywords = spinal, spina (Clic here for more details about this article) |
7/1288. spinal cord ganglioglioma in a child with neurofibromatosis type 2. Case report and literature review.Gangliogliomas of the spinal cord are rare disease entities that occur in early childhood. Their occurrence in association with neurofibromatosis Type 2 (NF2) has not been described. The authors describe the unique case of a 2-year-old child with stigmata of NF2 who harbored a spinal cord ganglioglioma that presented as a rapidly growing, exophytic intramedullary mass lesion at the cervicomedullary junction. Treatment consisted of complete surgical resection. Histopathological analysis of the lesion demonstrated a mixed population of neoplastic cells, of both neuronal and glial lineage, that supported the diagnosis of ganglioglioma.- - - - - - - - - - ranking = 0.4keywords = spinal, spina (Clic here for more details about this article) |
8/1288. De novo development of a cavernous malformation of the spinal cord following spinal axis radiation. Case report.Analysis of recent reports has suggested that cavernous malformations (CMs) of the brain may have an acquired pathogenesis and a dynamic pathophysiological composition, with documented appearance of new lesions in familial cases and following radiotherapy. The authors report the first case of demonstrated de novo formation of an intramedullary CM following spinal radiation therapy. A 17 year-old boy presented with diabetes insipidus and delayed puberty. Evaluation of endocrine levels revealed hypopituitarism, and magnetic resonance (MR) imaging demonstrated an infundibular mass. The patient underwent a pterional craniotomy and removal of an infundibular germinoma. The MR image of the spine demonstrated normal results. The patient received craniospinal radiation therapy and did well. He presented 5 years later with acute onset of back pain, lower-extremity weakness and numbness, and difficulty with urination. An MR image obtained of the spine revealed an intramedullary T-7 lesion; its signal characteristics were consistent with a CM. The patient was initially managed conservatively but developed progressive myelopathy and partial brown-sequard syndrome. Although he received high-dose steroids and bed rest, his symptoms worsened. He underwent a costotransversectomy and excision of a hemorrhagic vascular lesion via an anterolateral myelotomy. Pathological examination confirmed features of a CM. The patient has done well and was walking without assistance within 4 weeks of surgery. De novo genesis of CMs may be associated with prior radiation therapy to the spinal cord.- - - - - - - - - - ranking = 2.2keywords = spinal, spina (Clic here for more details about this article) |
9/1288. Intraspinal epidermoid cyst occurring 15 years after lipomyelomeningocele repair. Case report.The authors report the case of a spinal epidermoid cyst that developed in a patient who had undergone surgery for lipomyelomeningocele repair 15 years earlier. The patient presented with symptoms of retethering. magnetic resonance imaging revealed a cystic intraspinal mass that extended from L-2 to L-5. The mass proved to be an epidermoid cyst. Spinal epidermoid cysts can cause retethering after a repair of lipomyelomeningocele, and the risk of this development can be present for decades.- - - - - - - - - - ranking = 1.2keywords = spinal, spina (Clic here for more details about this article) |
10/1288. Spinal subarachnoid hemorrhage attributable to schwannoma of the cauda equina.BACKGROUND: cauda equina syndrome occurring as a result of spontaneous spinal subarachnoid hemorrhage (SAH) from a spinal tumor is reported to be rare. CASE DESCRIPTION: A 28-year-old woman presented at our clinic with a history of severe back pain for 10 days, progressive paraparesis, and urinary retention. Her physical examination revealed a mass located intradurally at the level of L1-2 and a massive SAH. An L1-L2, laminectomy and a hemilaminectomy from D9 to D12 were performed and the SAH was evacuated and the cord was decompressed. CONCLUSION: At the first year follow-up, her restricted dorsal and plantar flexion continued. Post-gadolinium magnetic resonance imaging revealed no mass.- - - - - - - - - - ranking = 0.4keywords = spinal, spina (Clic here for more details about this article) |
