1/173. 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 = 1keywords = nerve (Clic here for more details about this article) |
2/173. Cutaneomeningospinal angiomatosis (Cobb syndrome) with tethered cord.A newborn presented with a skin-covered lumbar mass with a subcutaneous hemangioma and on a magnetic resonance image (MRI) revealed a tethered spinal cord with a local mass. The mass had signal characteristics compatible with a lipoma. An initial diagnosis of a lipomeningocele with tethered cord was made, and the patient underwent surgical exploration and subtotal resection of the mass. A follow-up MRI revealed that the cord was still tethered, but an additional mass was present. The initial mass with signal characteristics of lipomatous tissue was accompanied by a low-signal mass in the lumbosacral canal, ventral to the cord, and bilateral enlargement of the foramina at the lumbosacral level. Because of a concern for an intraspinal tumor, a second operative intervention was performed. Multiple biopsies of the mass inside the spinal cord, the nerve roots and at the level of the foramina revealed angiomas that had similar pathology in all the specimens. A partial resection of the masses and a release of the tethered cord was performed by sectioning the thickened filum terminale. The diagnosis of Cobb's syndrome was made. The unique association of a tethered cord and the Cobb syndrome is reported here.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
3/173. Diffuse neonatal hemangiomatosis with extensive involvement of the brain and cervical spinal cord.BACKGROUND: Diffuse neonatal hemangiomatosis (DNH) is a rare disorder first recognized at birth or during the neonatal period. DNH is characterized by numerous cutaneous and visceral hemangiomas involving three or more organ systems. MATERIALS AND methods: Although the skin and liver are most frequently affected, we present a case of DNH demonstrating an unusual predilection for the central nervous system (CNS). RESULTS AND CONCLUSION: We report the imaging findings in a patient with this disorder, paying particular attention to the features seen on cranial sonography and spinal MR imaging.- - - - - - - - - - ranking = 0.0090000280786keywords = organ (Clic here for more details about this article) |
4/173. association of lower cranial nerve schwannoma with spinal ependymoma in ? NF2.A 15 year old male, who had earlier been operated for intraspinal intramedullary ependymoma, subsequently developed a right cerebello pontine (CP) angle mass. A diagnosis of right CP angle ependymoma was considered, in view of established histology of previously operated spinal lesion. Histopathological examination of the well defined extra-axial mass, which was attached with ninth cranial nerve, however revealed a schwannoma. A diagnosis of Neurofibromatosis-2 (NF2) is strongly suspected, because of well established fact, that the spinal ependymomas may have association with lower cranial nerve schwannomas in NF2. Cranial and spinal MRI screening for early diagnosis of associated, asymptomatic lesions, in suspected cases of NF2, particularly in children, is recommended.- - - - - - - - - - ranking = 6keywords = nerve (Clic here for more details about this article) |
5/173. Paragangliomas of the spinal canal.We report the clinical MRI and histopathological features of five consecutive cases of spinal paraganglioma. Three intradural tumours were found in the typical location (two at the L4, one at the S2 level); one intradural extramedullary tumour arose at an unusual level, from the ventral C2 root, and one extradural tumour growing along the L5 nerve root sheath had an aggressive growth pattern with early, local paraspinal recurrence and, eventually, intradural metastatic spread. This type of growth pattern has not been described previously. Paragangliomas of the spinal canal are more common than previously thought and can be located anywhere along the spine, although the lumbosacral level is the most common. Their appearance on MRI can not distinguish them from other tumours in the spinal canal. Even though paragangliomas in general are benign and slowly growing their growth pattern can vary and be more aggressive, to the point of metastatic spread.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
6/173. Malignant spinal neurofibrosarcoma.STUDY DESIGN: A report of a case of metastatic spinal neurofibrosarcoma. OBJECTIVE: To document metastatic neurofibrosarcoma as a cause of spinal cord compression and to review the literature. SUMMARY OF BACKGROUND DATA: Three previously reported cases of metastatic neurofibrosarcoma of the spine were reviewed. methods: The patient's clinical record and radiologic investigations as well as the result of a search of the English literature are reported. Magnetic resonance images, computed tomographic scans, and histology photomicrographs are displayed. RESULTS: paraparesis developed in this patient, due to a posterior extradural thoracic spinal cord compression by a neurofibrosarcoma believed to be metastatic from a neurofibrosarcoma of the femoral nerve. CONCLUSIONS: Malignant spinal metastasis remains a rare complication of neurofibromatosis, with a very poor prognosis.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
7/173. Multiple hemangiomas (hemangiomatosis) of the cauda equina and spinal cord. Case report.A case of multiple hemangiomas of the cauda equina nerve roots, conus medullaris, and lower spinal cord is described. The 74-year-old male patient presented with a 9-month history of progressive bilateral leg weakness. He had a history of lymphoma at the age of 39 years and renal cell carcinoma in his early 40s. Neither disease was evident at the time of this presentation. A magnetic resonance image revealed multiple enhancing nodules in the cauda equina region as well as on the pial surface of the lower thoracic spinal cord and conus medullaris. The patient underwent an L2-3 laminectomy. cauda equina nerve roots were found to be studded with numerous purple nodules, the largest measuring 6 to 8 mm. The nodules were adherent to nerve roots from which they could not be resected. Two lesions were histologically examined and found to be capillary hemangiomas. Twelve months into an uneventful postoperative course, the patient is neurologically unchanged. This unique case might represent a distinct form of hemangiomatosis confined to the cauda equina nerve roots and spinal cord.- - - - - - - - - - ranking = 4keywords = nerve (Clic here for more details about this article) |
8/173. Intradural spinal lipoma of the conus medullaris without spinal dysraphism.A 42-year-old man suffering from progressive left radicular sensory motor loss (L4 level) underwent neurosurgical repair. neuroimaging (RMI) had led to the diagnosis of schwannoma of the filum terminale with lipomatous component. Histological examination visualized a true mature lipoma associated with numerous bundles of more or less dystrophic nerve fibers. This histological benign tumor raised the problem of the genesis of intradural lipomas of spinal cord.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
9/173. Intramedullary spinal cord metastasis from gastric cancer. Case report.A case of intramedullary spinal cord metastasis from gastric cancer is reported. A 51-year-old woman presented with hemicord syndrome that had progressed within 1 month to tetraplegia. Despite total resection of the tumor, she died of disseminated intravascular coagulation and multiple organ failure. Examination of pathological findings demonstrated undifferentiated adenocarcinoma, and postoperative gastroendoscopic study revealed advanced gastric cancer. To the authors' knowledge this is the first case of intramedullary spinal cord metastasis from gastric cancer. The clinical characteristics of the disease are discussed.- - - - - - - - - - ranking = 0.0090000280786keywords = organ (Clic here for more details about this article) |
10/173. Capillary hemangioma of the spinal cord. Report of four cases.The authors describe the clinicopathological features of four cases of capillary hemangioma of the spinal cord. All occurred in adult patients. The presenting symptoms were similar to those of more common intramedullary tumors. Radiologically, they resemble other vascular spinal cord tumors. All patients underwent surgery, and the outcomes varied. Histologically, the lesions resembled capillary hemangioma of skin or of soft tissue that is composed of lobules of small capillaries with associated feeding vessels, all enveloped by a delicate fibrous capsule. Capillary hemangiomas of the central and peripheral nervous system are extremely rare. Although examples of these lesions have been described as occurring in the dura mater and in peripheral nerve, including spinal nerve roots, none has occurred within the spinal cord. knowledge of their existence may help practitioners to avoid misdiagnosis of tumor and resultant overtreatment of these benign lesions.- - - - - - - - - - ranking = 2keywords = nerve (Clic here for more details about this article) |
