BACKGROUND: Infections of the central nervous system (CNS) are common and routinely encountered. Our aim was to evaluate the neuroimaging features of the various infections of the CNS so as to differentiate them from tumoral, vascular, and other entities that warrant a different line of therapy. AIMS: Our aim was to analyze the biochemical and magnetic resonance imaging (MRI) features in CNS infections. SETTINGS AND DESIGN: This was a longitudinal, prospective study over a period of 1½ years...

The aim of the article is to describe the principal findings among patients with M.tuberculosis and M. bovis CNS infection. Mycobacterium tuberculosis is one of the most common infectious agents that cause death and neurological sequelae around the world. Most of the complications of CNS TB can be attributed to a delay in the diagnosis. Unfortunately, there are no specific diagnostic tools to support an early diagnosis. Other prognostic factors different from delay in treatment have not been identified. Clinical, radiological and laboratory characteristics were analyzed retrospectively from the medical files of all the patients admitted with the diagnoses of tuberculosis...

Diagnosis of tuberculous meningitis (TBM) is always a challenge. We must give importance for duration of clinical manifestations. Cerebrospinal fluid (CSF) has own characteristic and it have to be control several times during the treatment. Adenosin deaminase with cut off more than 15 UI/mL and M. tuberculosis polymerase chain reaction in CSF are the most relevant diagnostic tests. Radiologic test gives diagnostic clues but do not confirm the diagnosis. In the future we can structure a score with all these elements to support the clinician in the diagnostic process...

Tuberculous meningitis (TBM) is a severe infection of the central nervous system, particularly in developing countries. Prompt diagnosis and treatment are necessary to decrease the high rates of disability and death associated with TBM. The diagnosis is often time and labour intensive; thus, a simple, accurate and rapid diagnostic test is needed. The adenosine deaminase (ADA) activity test is a rapid test that has been used for the diagnosis of the pleural, peritoneal and pericardial forms of tuberculosis. However, the usefulness of ADA in TBM is uncertain...

Interferon-gamma release assay (IGRA) using specific tuberculous antigens is a rapid, specific and sensitive method for the detection of tuberculous infection, and usually done in peripheral blood sample. We examined IGRA in cerebrospinal fluid (CSF) in a patient strongly suspected of having tuberculous meningitis. A 53-year old woman had a month history of headache and fever with meningeal sign. Routine systemic bacterial, tuberculous and viral analyses all resulted in negative study except for increase of adenosine deaminase in CSF...

SUMMARY AND KEY RECOMMENDATIONS: The aim of these guidelines is to describe a practical but evidence-based approach to the diagnosis and treatment of central nervous system tuberculosis in children and adults. We have presented guidance on tuberculous meningitis (TBM), intra-cerebral tuberculoma without meningitis, and tuberculosis affecting the spinal cord. Our key recommendations are as follows: 1. TBM is a medical emergency. Treatment delay is strongly associated with death and empirical anti-tuberculosis therapy should be started promptly in all patients in whom the diagnosis of TBM is suspected...

We report a 31-year-old man with tuberculous meningitis (TM) mimicking CNS sarcoidosis. Although Mycobacterium tuberculosis (MTB) was not detected in CSF, the level of adenosine deaminase (ADA) in CSF was significantly raised. Brain biopsy showed caseous granuloma and a diagnosis of TM was made. The diagnosis of TM is often difficult and brain biopsy should be considered if MTB is not detected in the CSF. Evaluation of CSF ADA level could also strongly contribute to distinguishing TM from other meningitis. In addition to antituberculosis drugs, corticosteroid therapy was effective in our patient but careful reduction of its dosage was required...

A 34-year-old man visited the hospital with chief complaints of headache, fever, and disturbance of consciousness. In view of his clinical condition, the course of the disease, and results of examination, he was diagnosed with viral meningitis and treated accordingly. However, his clinical condition worsened, and MRI revealed abnormal signals in the splenium of the corpus callosum, in the basal ganglia and in the internal capsule, as well as the presence of severe inflammation in the base of the brain. Since he had a high ADA level in the cerebrospinal fluid and was consequently suspected to have tuberculous meningitis, he was placed on antitubercular agents...

We developed a diagnostic and therapeutic algorithm for intracranial mass lesions in patients with HIV/AIDS that obviates the need for neurosurgical intervention. The approach is based upon CD4(+) lymphocyte count, serum toxoplasma immunoglobulin G (IgG) serology, chest X-ray, routine lumbar puncture studies, cerebrospinal fluid (CSF) cytology, CSF adenosine deaminase or Mycobacterium tuberculosis polymerase chain reaction testing, single positron emission-computed tomography (SPECT) scanning for intracranial enhancing lesions, and limited therapeutic trials...

In the 1980s, after a steady decline during preceding decades, there was a resurgence in the rate of tuberculosis in the United States that coincided with the acquired immunodeficiency syndrome epidemic. Disease patterns since have changed, with a higher incidence of disseminated and extrapulmonary disease now found. Extrapulmonary sites of infection commonly include lymph nodes, pleura, and osteoarticular areas, although any organ can be involved. The diagnosis of extrapulmonary tuberculosis can be elusive, necessitating a high index of suspicion...

In spite of recent advances in diagnosis and chemotherapy of tuberculosis, prognosis of tuberculosis of the central nervous system (CNS) is still poor. We evaluated clinical characteristics of 14 patients with the CNS tuberculosis (10 male and 4 female, 21 to 71 years of age) who were hospitalized at IMCJ from 1988 to 1997. Twelve patients had tuberculous meningitis (2 of them had also intracranial tuberculoma), 1 had intracranial tuberculoma and 1 had spinal cord tuberculosis. For the acid-fast bacilli, the smears of cerebrospinal fluids (CSF) were all negative but the cultures for M...

The aim of this work was to study the usefulness of CSF adenosine deaminase determination in the diagnosis of tuberculous meningitis and determine if the proposed cutoff value of 7.1 i.u./ml had the better sensitivity and specificity. We retrospectively studied 148 patients, 12 with tuberculous meningitis and 136 with other central nervous system diseases. Adenosine deaminase values ranged from 3.6 to 31.2 i.u./ml in patients with tuberculous meningitis and from 0.1 to 312 i.u./ml in controls. The best sensitivity/specificity ratio (83...

The diagnostic value of adenosine deaminase (ADA) activity was studied to evaluate its use in the differential diagnosis of tuberculous meningitis in the local setting. Cerebrospinal fluid (CSF) from 119 patients with meningitis and other conditions with central nervous system symptoms were collected and ADA activity determined by the colorimetric method of Guisti read at 628 nm. The CSF was also subjected to other laboratory examinations so as to provide the aetiological diagnosis. All 14 tuberculous meningitis patients had ADA activity greater than the cut off value of 9...

The adenosine deaminase (ADA), lysozyme (LZM) and lactate dehydrogenase (LDH) of serum and cerebrospinal fluid (CSF) were determined in 36 patients with tuberculous meningitis (TBM), 47 patients with non-tuberculous meningitis (N-T-BM) and 20 patients with non-central nervous system diseases(control group). The results showed that the assessment of serum and CSF ADA and LZM activity may be helpful to the differential diagnosis between TBM and N-TBM.

We measured the activity of adenosine deaminase (ADA) in the cerebrospinal fluid of 3 patients with tuberculous meningitis, 38 with viral meningitis, 15 with bacterial meningitis, 5 with malignant lymphoma, 11 with cerebrovascular diseases and 13 with miscellaneous neurological disorders. The highest ADA activities were observed in patients with tuberculous meningitis (median 21.3 U/l, range 20.0-23.0) and lymphoma (13.0 U/l, range 4.0-25.0). The sensitivity of the test for diagnosing tuberculous meningitis was 100% and the specificity 99% when a cut-off value of 20...
