Identify the clinical and radiologic findings in tuberculosis affecting the central nervous system. Describe the differential diagnosis and appropriate imaging work-up for this infectious process.
We report a retrospective study that evaluates 40 cases of tuberculosis involving the central nervous system seen during three year- period from January 2009 to December 2011. Patients were admitted with variant clinical features: headache,
1 All the patients were evaluated with CT scan or MRI or both. All diagnoses were confirmed by biological and/or histopathological analysis .

The results that were obtained: Fig.
2 Meningitis (n=12), encephalitis (n=3), tuberculoma(n=8), tuberculous brain abscess (n=3), tuberculous vasculitis (n=2), myelitis (n=4), spinal tuberculosis (n=7), calvarial tuberculosis(n=1). MENINGEAL TUBERCULOSIS Tuberculous meningitis (TBM) is the most common presentation of neurotuberculosis and occurs predominantly in young children and adolescents. Clinical features TBM most often presents with fever,
decreased level of consciousness,
The clinical and radiologic patterns of tuberculosis may mimic those of many other diseases. It is imperative that radiologists and clinicians understand the spectrum of imaging features of central nervous system tuberculosis to aid in making an early diagnosis.
