Workshops 1 ). Chest radiographs are important in the evaluation and risk stratification of patients suspected of having latent or inactive tuberculosis. Proteomics Core Facility. Differential diagnosis of CNS TB includes multiple brain metastases (which associated with more edema); sarcoidosis (which are associated with parenchymal nodules and have multiple dural and/or leptomeningeal nodules, multifocal or multicentric primary tumour,and fungal infections. 20 (2): 471-88. Abnormal meningeal enhancement is seen in the basal cisterns, and sylvian fissures, and severe and late-stage TBM can show enhancement over the convexities ( Fig. `Imaging `Bioppysy . In a follow-up case of TB meningitis, T2W axial images show disproportionate enlargement of the left lateral ventricle (, TB vasculitis with acute infarct. This focus may be in the meninges, subpial or subependymal region of the brain, or the spinal cord. To familiar with epidemiology and pathophysiology of CNS tuberculosis 2. Tuberculosis (TB) is a global clinical concern, particularly after the human immunodeficiency virus pandemic. Localization of the cause of cranial nerve involvement, whether confined to the nerve or its brain stem nucleus, may help in prognostication of patients. Central nervous system (CNS) tuberculosis is frequently encountered in tropical countries. Life Sciences Training Facility. For further discussion please refer to separate articles on tuberculous leptomeningitis and tuberculous pachymeningitis. 5 ). Postcontrast T1W axial (, Photomicrograph of tuberculous granuloma. Patients usually present with headache, seizures, focal neurologic deficit, and features of raised intracranial tension. METHODS: A total of 107 tuberculomas in seven patients with or without meningitis and 15 patients with tuberculosis … • Greater prevalence in immunocompromised patients and is seen in ~ 15-20 % of cases of AIDS-related TB. 35. Tentorial and cerebellar meningeal involvement is less common. Tuberculomas show typical granulomatous reaction consisting of epithelioid cells, giant cells mixed with mononuclear inflammatory cells (predominantly lymphocytes) forming a noncaseating granuloma. `Considered disease of childhood however in India all age Considered disease of childhood , however in India all age groups susceptible . Granulomas may coalesce to form tuberculomas or, rarely, an abscess. The newer imaging techniques further help to improve the characterization and diagnosis of atypical CNS TB. The diagnosis and treatment of … The purpose of this study was to improve the characterization of lesions in CNS tuberculosis and to assess the disease load using magnetization transfer (MT) imaging. Magnetic resonance (MR) imaging has been shown to be superior to CT in evaluating patients with suspected meningitis and its associated complications. MR imaging also plays an important role in the postoperative evaluation of patients with endoscopic third ventriculostomy. Mycobacterium TB is the most common organism causing tuberculous infection of CNS. Identification of border zone encephalitis is difficult because the hyperintense T2 signal in these regions merges with the bright signal of the leptomeningeal exudate. CLINICAL RADIOLOGY OF CEREBRAL TUBERCULOSIS Dr. Rahi kiran.B SR Neurology GMC, KOTA 2. 7 ). Cell-mediated immunity is responsible for the formation of dense, gelatinous, inflammatory exudate along the basal surface of the cerebrum. Andronikou and colleagues suggested 9 criteria for the diagnosis of TBM on computed tomography (CT). Tuberculous pachymeningitis can be localized or diffuse.
