title: [Neuromeningeal tuberculosis: the contribution of genetic amplification to diagnosis].
abstract: Neurological manifestations of tuberculosis are rare, especially in immunocompetent subjects. The heterogeneity of clinical and radiological features induces frequently a delay for diagnosis. The aim of the study was to describe clinical and radiological presentation of 11 cases of neuro-tuberculosis and to evaluate clinical outcome. We performed clinical, CSF, MRI and outcome evaluation in all patients. We also performed a mycobacterium analysis by polymerase chain reaction (PCR). Patients were 6 men and 5 women with a mean age of 45.4 years. Clinical presentations were meningeal symptoms in 9 cases and focal manifestations in 4 cases. CSF was abnormal in 82 p.cent of cases (protein increase in 73 p.cent, pleiocytosis in 73 p.cent, hypoglycorrhachia in 45 p.cent and hypochlorrhachia in 36 p.cent). The best diagnostic test was PCR (positive in 45 p.cent of cases). CSF cultures were positive in only 2 cases (18 p.cent). Only 2 patients had chest involvement. MRI was abnormal in 64 p.cent of cases showing pseudo-tumor, arachnoiditis, vascular lesions or medullar involvement. Outcome was good in all cases but two (one patient died and one patient had paraplegia possibly related to late diagnosis). Neurological manifestations of tuberculosis are extremely various in terms of clinical and radiological presentation. The best diagnostic test seems to be tuberculosis PCR. Outcome is frequently favorable if late diagnosis is avoided.
