The case of a 67-year-old man with underlying carcinomatous meningitis who presented with meningismus and cerebrospinal fluid (CSF) eosinophilia is reported. CSF eosinophilia can reflect a number of underlying conditions; however, carcinomatous meningitis is not generally considered. In this case, studies for bacterial, fungal and parasitic agents were negative. Cytologic examination of a lumbar puncture specimen revealed malignant epithelial cells in an inflammatory background. When unexplained eosinophilia is found in the CSF, a thorough search for coincident meningeal carcinomatosis should be undertaken. 相似文献

Leptospirosis is a zoonotic disease caused by the pathogenic Leptospira spp. The clinical presentations are diverse, ranging from undifferentiated fever to fulminant disease including meningeal forms. The neurological leptospirosis forms are usually neglected. The aim of this study was to investigate leptospirosis as the cause of aseptic meningitis using different diagnostic techniques including the polymerase chain reaction (PCR). Thirty-nine cerebrospinal fluid (CSF) samples from patients presenting with meningeal abnormalities, predominance of lymphocytes and negative results by traditional microbiological tests were processed by leptospiral culture, anti-leptospiral antibody response and PCR. Leptospira spp DNA was detected in 23 (58.97%) of the CSF samples. Anti-leptospiral antibodies were found in 13 (33.33%) CSF samples. Twelve CSF samples were positive by PCR assay and negative by microscopic agglutination test (MAT) assay. Two CSF samples were positive by MAT and negative by PCR. The positive and negative agreement between both tests was 11 and 14, respectively. CSF samples from six cases of unknown diagnosis were positive by PCR assay. Eight cases showed positive results using PCR and MAT. Leptospirosis could be detected by PCR assay from the 3rd-26th day after illness onset. The sensitivity of the PCR was assessed with confirmed cases of leptospirosis (by MAT) and found to be 89.5%. All CSFs were negative by culture. PCR was found to be a powerful tool for diagnosing meningitis cases of leptospirosis. We recommend that it may be used as a supplementary diagnostic tool, especially in the early stages of the disease, when other diagnostic techniques such as serology are not sensitive. 相似文献

A 66-year-old man presented with a six-month history of neurologic symptoms suggestive of a craniospinal tumor or a diffuse inflammatory process in the subarachnoid space. Cytologic examination of cerebrospinal fluid (CSF) revealed inflammatory changes and malignant melanin-containing cells, leading to a diagnosis of meningeal spread of a melanoma. There was no history of skin excisions and no clinical evidence of primary melanoma of the eye. Neuroradiologic investigations, including CT and myelography, to confirm the diagnosis were negative. Despite intrathecal cytostatic therapy, the patient died eight months after the onset of symptoms. Autopsy disclosed diffuse meningeal melanoblastosis of the spinal cord and the base of the brain, confirming the cytologic diagnosis. In addition, two micrometastases in the liver were found as only extraneural manifestation. This case emphasizes the importance of CSF cytology in the diagnosis of diffuse infiltrating processes in the subarachnoid space. 相似文献

Of 52 children admitted to hospital for apparently typical mumps meningitis in 1966, 50 had their cerebrospinal fluid (CSF) examined. In only 17 was the mumps virus isolated from the CSF. Mumps antihemagglutinin conversions or increments were detected in 32 subjects including 10 whose CSF yielded virus. Antibody conversions were found in 16 patients and fourfold increments in another nine whose serum pairs were collected only one to four days apart. Initial sera from 20 patients were obtained three days or less after the onset of meningitis. Antibody increments were frequently noted about one day after defervescence and clinical improvement. Interferon was detected in CSF from two of eight patients, both of whom yielded virus. Enteroviruses were isolated from CSF and/or feces in seven of 15 cases of aseptic meningitis which occurred between July and October. Six patients including three virus excretors showed enteroviral neutralizing antibody increments during convalescence. The dominant enteroviral serotype was coxsackievirus A9. 相似文献

目的:探讨结核性脑膜炎颅神经损害与脑脊液特点的关系。方法:回顾性收集我院神经内科确诊的173例结核性脑膜炎患者临床资料,将所有患者分为伴颅神经损害和不伴颅神经损害两组,对其临床特点及脑脊液外观、压力及细胞学、生化、免疫球蛋白结果进行统计学分析。结果:颅神经损害者占所有病人的22.5%(39/173),视神经损害占61.5%(24/39),外展神经损害占53.8%(21/39),动眼神经损害占15.4%(6/39),听神经损害占15.4%(6/39);颅神经损伤组较无颅神经损伤组脑脊液压力、蛋白质及Ig G、Ig M、Alb明显升高(P0.01或0.001),且颅神经损害者头颅MRI脑膜强化较无颅神经损害者差异有统计学意义(P0.001),而脑脊液外观、白细胞计数及比例两组间并无发现显著差异。结论:结核性脑膜炎患者伴颅神经损害时,脑脊液压力、蛋白质及部分免疫球蛋白较无颅神经损害者明显升高,这将有助于结核性脑膜炎合并颅神经损害的临床诊断,对于有颅神经损害的结核性脑膜膜炎患者加强并早期启动抗结核治疗,以减少蛋白质沉积,从而降低颅神经损害的发生率。 相似文献

Clonal analysis of HLA-restricted virus-specific cytotoxic T lymphocytes from cerebrospinal fluid in mumps meningitis 总被引:4,自引:0,他引:4
T lymphocytes were cloned directly from the cerebrospinal fluid of a patient with mumps meningitis by limiting dilution in the presence of irradiated feeder cells and T cell growth factor. Of 84 colonies analyzed, 41 were cytotoxic, as shown by their ability to exert phytohemagglutinin-dependent killing. Of these, 39 showed specificity for the autologous mumps-virus infected target cells. The cytotoxic T cell colonies showed the same pattern of HLA restriction as bulk cultures of CSF lymphocytes. This study shows that it is possible to perform functional assays on inflammatory exudate cells at the clonal level. The data also suggest that recruitment of effector cells from the peripheral compartment into the meningeal spaces in mumps meningitis is highly antigen-specific. 相似文献

Background
Scrub typhus is prevalent in India although definite statistics are not available. There has been only one study on scrub typhus meningitis 20 years ago. Most reports of meningitis/meningoencephalitis in scrub typhus are case reportsMethods
A retrospective study done in Pondicherry to extract cases of scrub typhus admitted to hospital between February 2011 and January 2012. Diagnosis was by a combination of any one of the following in a patient with an acute febrile illness- a positive scrub IgM ELISA, Weil-Felix test, and an eschar. Lumbar puncture was performed in patients with headache, nuchal rigidity, altered sensorium or cranial nerve deficits.Results
Sixty five cases of scrub typhus were found, and 17 (17/65) had meningitis. There were 33 males and 32 females. Thirteen had an eschar. Median cerebrospinal fluid (CSF) cell count, lymphocyte percentage, CSF protein, CSF glucose/blood glucose, CSF ADA were 54 cells/µL, 98%, 88 mg/dL, 0.622 and 3.5 U/mL respectively. Computed tomography was normal in patients with altered sensorium and cranial nerve deficits. Patients with meningitis had lesser respiratory symptoms and signs and higher urea levels. All patients had received doxycycline except one who additionally received chloramphenicol.Conclusion
Meningitis in scrub typhus is mild with quick and complete recovery. Clinical features and CSF findings can mimic tuberculous meningitis, except for ADA levels. In the Indian context where both scrub typhus and tuberculosis are endemic, ADA and scrub IgM may be helpful in identifying patients with scrub meningitis and in avoiding prolonged empirical antituberculous therapy in cases of lymphocytic meningitis. 相似文献19.

We previously identified CCL20 as an early chemokine in the cerebrospinal fluid (CSF) of patients with pneumococcal meningitis but its functional relevance was unknown. Here we studied the role of CCL20 and its receptor CCR6 in pneumococcal meningitis. In a prospective nationwide study, CCL20 levels were significantly elevated in the CSF of patients with pneumococcal meningitis and correlated with CSF leukocyte counts. CCR6-deficient mice with pneumococcal meningitis and WT mice with pneumococcal meningitis treated with anti-CCL20 antibodies both had reduced CSF white blood cell counts. The reduction in CSF pleocytosis was also accompanied by an increase in brain bacterial titers. Additional in vitro experiments showed direct chemoattractant activity of CCL20 for granulocytes. In summary, our results identify the CCL20-CCR6 axis as an essential component of the innate immune defense against pneumococcal meningitis, controlling granulocyte recruitment. 相似文献
