We report a case of cerebral phaeohyphomycosis due to Wangiella dermaitidis in an immunocompetent adult man. His cerebrospinal fluid (CSF) showed pleocytosis with a high eosinophil count but without peripheral blood eosinophilia. The present case suggested that this black yeast-like fungus should be included when the causes of CSF eosinophilia are considered, even though it is an extremely rare...

We present a unique imaging presentation of Headache and Neurological Deficits with Lymphocytic pleocytosis (HaNDL) Syndrome. Case Report A Syndrome of Headache and Neurological Deficits with Cerebrospinal Fluid (CSF) Lymphocytic Pleocytosis (Handl) with Diffuse Vasogenic Leakage of Gadolinium MRI Contrast into the Extra-Axial CSF Cisterns Neema Patel1*, Vivek Gupta1, Kevin Barrett2, and Prasanna

Hepatitis C virus (HCV) sequences were detected in cerebrospinal fluid (CSF) in 8 of 13 HCV-positive patients. In four patients harboring different virus strains in serum and peripheral blood mononuclear cells (PBMC), CSF-derived virus was similar to that found in PBMC, which suggests that PBMC could carry HCV into the brain.

The final diagnosis of 158 patients who had a cerebrospinal fluid (CSF) lactate concentration greater than 2 mmol/l was ascertained. The conditions included seizures, inflammatory changes, and proven metabolic disorders. For the diagnosis of congenital lactic acidoses, CSF lactate should ideally be measured in a seizure free patient after any acute illness.

CXCL13 in cerebrospinal fluid (CSF) could be an important component for diagnosing Lyme neuroborreliosis (LNB). Levels of intrathecal CXCL13 were determined for 58 LNB patients and 210 controls; sensitivity was 88% and specificity was 89% (cutoff, 250 pg of CXCL13/ml of CSF). Elevated levels of CXCL13 can aid in the diagnosis of LNB, but levels should be interpreted with care.

The sensitivity and specificity of immunocytochemical staining of mycobacterial antigens in the cytoplasm of cerebrospinal fluid (CSF) macrophages for diagnosis of tuberculous meningitis (TBM) was prospectively compared with Ahuja criteria from 393 consecutive CSF specimens. The assay can play an important role for the diagnosis of TBM, with sensitivity of 73.5% and specificity of 90.7%.

Abdominal cerebrospinal fluid (CSF) pseudocyst is a rare complication of ventriculoperitoneal shunting. It is well known in children but uncommon in adults. We present a 30-year-old woman with abdominal distension, vomiting and confusion caused by her developing an abdominal CSF pseudocyst, 13 years after her last shunt revision. Adult neurologists need to be aware of this late complication.

A vervet monkey model of trypanosomiasis was used to study inflammatory cytokine responses in serum and cerebrospinal fluid (CSF). Gamma interferon levels were transiently up-regulated in serum between days 6 and 8 of infection, followed by a sustained up-regulation of tumor necrosis factor alpha (TNF-alpha) and soluble TNF receptor 1. At no time were these cytokines detectable in the CSF.

Poor prognosis in Pneumococcal meningitis may be associated with high pneumolysin levels in cerebrospinal fluid (CSF). In patient samples we showed that pneumolysin levels in CSF remained high after 48 hours in nonsurvivors of meningitis compared with survivors. Selective antipneumolysin treatment may present a novel therapeutic option.
