副肿瘤性小脑变性(paraneoplastic cerebellar degenertion,PCD)又称亚急性小脑变性(subacute cerebellar degeneration,SCD),是神经系统副肿瘤综合征(praneoplastic neurological syndrome,PNS)引起神经系统的典型损害之一,神经系统副肿瘤综合征(PNS)是一种罕见的副肿瘤综合征,并不是由肿瘤转移或直接浸润到神经系统引起,是由免疫反应的改变引起。是一种与恶性肿瘤相关但原因不明的小脑非转移性病变。本文报道1例以副肿瘤性小脑变性为首发症状的肺癌病例,加强临床医生对该病的认识。该患者即以双下肢行走不稳收入院,表现为小脑受损的症状与体征,脑干受损症状与体征未表现。检查脑脊液生化示,葡萄糖4.73 mmol/L,微量总蛋白548.00 mg/L;脑脊液抗酸、墨汁染色阴性。脑脊液常规示,红细胞数0,白细胞26个/mm~3;副肿瘤相关抗体抗Hu抗体阳性。行胸部增强CT示,左肺上叶前段占位病变,考虑新生物;左肺上叶尖后段纤维条灶索;纵隔内及左肺门区多发淋巴结肿大。结合患者临床表现和辅助检查,临床诊断为副肿瘤性小脑变性。早期诊断副肿瘤性小脑变性对于及时发现和根除宿主体内的肿瘤至关重要,尤其小细胞肺癌、乳腺癌、卵巢癌等。有条件可在血液和脑脊液中检测特定的抗神经元抗体,目前发现许多抗神经元抗体与PCD有关,并且对特定的肿瘤类型的早期诊断提供依据,如抗Hu抗体提示小细胞肺癌,抗Yo抗体提示乳腺、卵巢等肿瘤。该病总体预后不良,应积极采取综合治疗手段,控制肿瘤的转移及复发,以提高患者生存质量,延长生存时间,改善生存率。 相似文献

OBJECTIVE: To review the clinical, laboratory, and radiological findings of 9 patients who had progressive idiopathic myelopathy with evidence of spinal cord necrosis. DESIGN AND METHODS: We reviewed personally examined cases of myelopathy that fulfilled the following criteria: (1) regional loss of reflexes, flaccidity, and muscle atrophy; (2) magnetic resonance imaging showing a shrunken or cavitated cord without evidence of arteriovenous malformation; (3) electromyogram showing denervation over several contiguous spinal cord sgements with preservation of sensory potentials in some cases; and (4) the absence of evidence of systemic disease or neoplasm. RESULTS: The illness began in these patients after the age of 40 years, with prominent burning or tingling limb pain, occasionally with radicular features or with less well-defined back, neck, or abdominal pain. Leg or infrequently arm weakness appeared concurrently or soon after the onset of pain. The most distinctive feature was a saltatory progression of symptoms, punctuated by both acute and subacute worsenings approximately every 3 to 9 months, culminating in paraplegia or tetraplegia. The distinguishing clinical findings, together indicative of destruction of gray matter elements of the cord, were limb atrophy, persistent areflexia, and flaccidity. The concentration of cerebrospinal fluid protein was typically elevated between 500 g/L and 1000 g/L, without oligoclonal bands, accompanied infrequently by pleocytosis. Magnetic resonance imaging showed features suggesting cord necrosis, specifically swelling, T2-weighted hyperintensity, and gadolinium enhancement over several spinal cord segments, succeeded months later by atrophy in the same regions. Necrosis of the cord was found in biopsy material from one patient and postmortem pathology in another case, but inflammation and blood vessel abnormalities were absent. Only 2 patients had prolonged visual evoked responses. The disease progressed despite immune-modulating treatments although several patients had brief epochs of limited improvement. CONCLUSIONS: The saltatory course, prolonged visual evoked responses in 2 patients, and a cranial abnormality on magnetic resonance imaging in another, raised the possibility of a link to multiple sclerosis. However, the normal cranial magnetic resonance imaging scans in 6 other patients, uniformly absent oligoclonal bands, and poor response to treatment were atypical for multiple sclerosis. On the basis of shared clinical and laboratory features, idiopathic progressive necrotic myelopathy is indistinguishable from a limited form of Devic disease. 相似文献

This case series reviews the clinical, radiographic and laboratory findings of five patients with progressive idiopathic myelopathy with evidence of cord necrosis who presented in our institution over a 5 year period ending in May 2005. Patients fulfilling the following criteria were included: (1) presentation with myelopathy without overt visual involvement at initial presentation; (2) demonstration with magnetic resonance imaging (MRI) of contiguously abnormal signal in the spinal cord spanning at least three vertebral segments without evidence of arteriovenous malformation or significant disk disease; (3) absence of systemic disease or neoplasm. All patients were women, identified themselves as African American and were older than 35 years. Pain was reported at initial presentation in four cases. The distinctive feature was a relapsing course with intervening variable improvement of function and progression to quadriplegia in less than 4 years. An increased IgG index and/or oligoclonal banding was detected in two patients. The leukocyte count in the cerebrospinal fluid (CSF) was elevated in all cases but in only one specimen did the count exceed 50 cells. None of the patients initially had clinical signs of an optic neuropathy but unilaterally prolonged visual evoked potentials were present in one individual who went on to developed optic neuritis 19 months after the first clinical presentation. Another patient developed optic neuritis 45 months after disease onset. Immunomodulatory and plasma exchange therapy were of some benefit at least early in the course but the disease progressed despite these interventions. Neuromyelitis optica (NMO)-IgG antibody, a serum or CSF marker described in individuals with classic NMO and optico-spinal multiple sclerosis (MS), was present in all cases. On the basis of shared clinical and imaging features in the cord, progressive necrotizing myelopathy observed in this case series exhibits key features of a limited form of NMO (Devic's disease) and opticospinal MS. The presence of NMO-IgG antibody marker suggests that progressive necrotizing myelopathy is part of a disease spectrum of which traditional NMO is a select presentation. 相似文献

The occurrence of visceral larva migrans due to Ascaris suum (A. suum) and Toxocara canis (T. canis) has occasionally been reported in Japan, although parenchymatous involvement of the CNS is extremely rare in A. suum/T. canis visceral larvae migrans. Recently we experienced 7 cases with myelitis caused by visceral larva migrans due to A. suum/T. canis (parasite myelitis). The characteristics of this myelitis are: (1) sensory disturbances (Lhermitte's sign, paresthesia, and hypesthesia) are predominant symptoms, while severe motor weakness is rare, (2) spinal cord lesions on T2-weighted MRI show more extensive lesions compared with mild symptoms, (3) Gadolinium enhancement of spinal cord lesions are limited as compared with spinal cord lesions on T2-weighted MRI lesions, (4) Some cases show the presence of eosinophils in CSF, while others show Th2 deviation in CSF supernatant, and (5) Tests for anti-A. suum/T. canis IgG antibody are strongly positive in serum and CSF. Moreover, 6 percent of 108 consecutive cases with non-compression myelopathy presenting at the Department of Neurology at Kyushu University Hospital from January, 1998 to December, 2002 had parasitic myelitis. Myelitis from visceral larva migrans due to A. suum/T. canis might be overlooked because of its mild neurologic impairment without systemic symptoms, but should be considered as one of the differential diagnoses in non-compression myelopathy. 相似文献

Seven patients with isolated spinal cord symptoms, and with evoked potential (EP) recordings and/or cerebrospinal fluid (CSF) findings supporting a demyelinating cause for their myelopathy, were examined with cervical and cranial magnetic resonance imaging (MRI). Lesions in the cervical spinal cord were detected in 6 of the patients, including 2 who also had disseminated lesions in the brain compatible with multiple sclerosis (MS). In one patient MRI of the cervical spinal cord was normal, while plaques were seen in the periventricular region of the brain and in the brain stem. Thus, in the 3 patients with cerebral plaques, MRI supported the diagnosis of MS by showing dissemination in space. In the remaining 4 patients MRI provided support for the diagnosis of MS by demonstrating the cervical spinal cord plaques while excluding other potential causes of myelopathy, such as spinal cord compression and intramedullary tumor. 相似文献

Detection of the 14-3-3 protein in the cerebrospinal fluid of Japanese multiple sclerosis patients presenting with severe myelitis 总被引:5,自引:0,他引:5

Recent studies showed that the 14-3-3 protein is detectable in the cerebrospinal fluid (CSF) of prion-unrelated neurological diseases, such as meningoencephalitis and myelitis. To investigate the possible association between the amounts of the 14-3-3 protein in the CSF and the clinical severity of multiple sclerosis (MS), its levels were determined by Western blot in the CSF of the patients with relapsing-remitting MS (RRMS) (n=10), secondary progressive MS (SPMS) (n=7), primary progressive MS (PPMS) (n=2), and non-MS inflammatory diseases of the CNS (n=5). The 14-3-3 protein was identified in seven CSF samples, including four patients with SPMS in acute relapse, one with SPMS in remission accompanied by fresh cerebral infarction, one with RRMS in acute relapse, and one with human T-lymphotropic virus type I (HTLV-I)-associated myelopathy. The patients positive for the CSF 14-3-3 protein immunoreactivity showed more severe disability and higher levels of pleocytosis, protein, IgG, beta2-microglobulin, and neuron-specific enolase in the CSF, compared with those negative for its immunoreactivity. Four of these patients exhibited extensive lesions distributed along multiple vertebral segments in the spinal cord on MRI. In contrast, none of the MS patients without an extensive involvement of the spinal cord showed the CSF 14-3-3 protein immunoreactivity. These results suggest that detection of the 14-3-3 protein in the CSF provides a marker for severe inflammation-induced extensive damage of the central nervous system tissues responsible for poor therapeutic responses and irreversible neurological deficits in MS. 相似文献

Intracranial hypotension typically presents following cerebrospinal fluid (CSF) leak, but can be induced by CSF diversion. Classically, patients present with positional headache, but less common symptoms include neck pain and cranial nerve palsies. To our knowledge, the neurosurgical literature contains six reports of patients with symptomatic cervical, epidural venous plexus engorgement as the result of CSF shunting. The patient presented herein is a 26-year-old woman with shunt-dependent, congenital hydrocephalus. She presented with rapidly progressive cervical myelopathy following ventriculoperitoneal shunt revision. Imaging revealed engorgement of the cervical epidural venous plexus and mass effect on the cervical spinal cord. “Over-shunting associated myelopathy” is a rare complication of CSF diversion that should be familiar to physicians who routinely evaluate patients with intracranial shunts. 相似文献

Transverse myelopathy is an uncommon complication of systemic lupus erythematosus (SLE). Three patients with SLE are reported who developed transverse myelopathy, including the neuropathological findings in one patient on whom necropsy was performed. Paraparesis was present in all three cases, but definite sensory changes were present in only one patient. In two patients, the CSF findings were remarkable for elevated protein and depressed glucose concentrations. Microscopic examination of the brain demonstrated small, scattered foci of recent necrosis consistent with microinfarctions. Striking abnormalities were found in the spinal cord at all levels, including multiple foci of vacuolar spongy degeneration in the peripheral white matter, as well as ballooning of myelin sheaths, swollen axons, myelin pallor, and loss of glial nuclei. The pathological findings in previously reported cases of SLE-related transverse myelopathy are reviewed, and the possible pathogenesis of the findings in our case are discussed. 相似文献

Myelopathy in patients with antiphospholipid antibodies: clinical features, pathogenesis, and review of literature] 总被引:1,自引:0,他引:1

We report 5 patients with anti-cardiolipin IgM-positive myelopathy. The lengths of spinal lesions were over two vertebral segments in 4 patients. Four cases showed subacute onset, and 2 out of these 4 cases had inflammatory changes in cerebrospinal fluid (CSF), and all of their symptoms improved. However, in one patient who showed an acute onset and normal findings of CSF, neurological symptoms did not improve. Three patients fulfilled the diagnostic criteria of primary antiphospholipid antibody syndrome. As for the pathophysiology of myelitis associated with antiphospholipid antibodies (aPL), it is suggested that vascular thrombosis affecting the blood cord barrier promotes an inflammatory changes. The heterogeneous CFS findings seem to reflect the difference in the intensity of inflammation. Both vascular thrombosis and inflammatory process should be considered as pathogenesis of these patients. Alone or combination therapy of steroids and anticoagulants might be effective in patients of myelopathy associated with APS. 相似文献

Spontaneous spinal cord herniation through a dural defect is an unusual condition. This entity has been probably underestimated before the introduction of MRI. We report a case of a 49-year-old man with a progressive Brown-Sequard syndrome. MRI and CT myelogram showed a ventrally displaced spinal cord at level T6-T7 and expansion of the posterior subarachnoid space. Through a laminectomy, a spinal cord herniation was identified and reduced. The anterior dural defect was repaired with a patch of lyophilized dura. The patient recovered muscle power but there was no improvement of the sensory disturbance. The diagnosis of spontaneous spinal cord herniation must be considered when progressive myelopathy occurs in middle-aged patients, without signs of spinal cord compression and typical radiological findings. Surgical treatment may halt the progressive deficits and even yield improvement in many cases. 相似文献

We report a case of HTLV-I associated myelopathy (HAM) with a spinal cord MRI showing abnormal multifocal and patchy lesions. A 50-year-old woman suffering from progressive paraparesis was admitted to our hospital. HTLV-I antibodies in the serum and CSF were positive, and a diagnosis of HAM was made. Her T2 weighted spinal cord MRI showed scattered areas of high signal intensity from the cervical to the thoracic cord. The lesions were enhanced with gadolinium-DTPA on T1 weighted imaging. Atrophy of the thoracic cord has been reported in many patients with HAM. In rare cases, T2 weighed thoracic cord MRI showed diffuse high signal intensity. The pattern of high signal intensity in our case, however, was multifocal and patchy, thus differing from the findings of previous reports. And we believe this is the first such report. This case suggests that the MRI of HAM patient may show multifocal and scattered lesions in the spinal cord. 相似文献
