RESUMO
Tuberculosis is a public health problem in Morocco. Central nervous system involvement is nevertheless rare, occurring in the context of multifocal or miliary tuberculosis. However, it may be a mode of revelation even in an immunocompetent subject. We report the case of a 30-year old man with language disorder accompanied by significant impairment of general condition. Clinical examination showed Broca's motor aphasia, right-sided pyramidal syndrome and latero-cervical adenopathies. HIV serologic test was negative. Brain MRI showed lesions associating multiple intracranial tuberculomas and meningoencephalitis. Thoracic CT scan showed multiple pulmonary micronodules, cavity wall thickening and bronchiectasia of the right fowler and culmen. Lymph node biopsy revealed typical architecture of a TB granuloma. The diagnosis of multifocal tuberculosis was retained and the patient received anti-bacillary therapy associated with corticosteroid therapy with good clinico-radiological evolution. This study is peculiar due to the appearance and the seat of tuberculous lesions on brain imaging, the absence of immunodeficiency, a good evolution under treatment. It highlights the role of active and exhaustive assessment of associated extracerebral tuberculous infection in the case of cerebromeningeal lesion suggestive of tuberculosis.
