title: [Tuberculous meningitis in an immunocompetent adult: contribution of cerebral imaging techniques to the diagnosis and follow-up].
abstract: We have studied 5 men, mean age 47 years, affected by tuberculous meningitis (TM) without documented immunodepression. The diagnosis of TM was supported by clinical and biological investigations and confirmed by the cultures of CSF. All the patients received a four-drug combination therapy and steroids. No drug resistance of the bacilli was observed. Cerebral imaging by CT and MRI was rarely diagnostic but most useful during the follow-up. All the patients developed complications including tuberculomas (5), hydrocephalus (4), ischemic lesions (2), arachnoiditis (1) and abscess of spinal cord (1). Four patients recovered and one died. The mean duration of the follow-up was 16 months. MRI was more sensitive than CT scan to identify inflammatory lesions such as granulomas, angeitis or arachnoiditis and to follow their outcome. Tuberculomas and hydrocephalus were easily diagnosed by CT scan with contrast enhancement. Recommendations of sequential imaging are suggested to identify unexpected or asymptomatic complications of TM during therapy and evaluate the outcome.
