Abstract:
Diffuse pachymeningitis is an uncommon presentation of tuberculous meningitis (TBM). We present a 78-year-old woman patient with a 1-year history of progressive headache and MRI of the brain compatible with diffuse pachymeningitis. Without strong evidence to support a diagnosis, she subsequently underwent dural biopsy which revealed caseous granulomatous inflammation and was positive for Mycobacterium tuberculosis complex by PCR. The dura tissue culture subsequently confirmed the diagnosis of TBM. Successful treatment with antituberculous drugs and corticosteroid was observed without complications. Literature review on characteristics, diagnoses and treatment of central nervous system tuberculosis was also performed.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
