In this work, 1,000 cases of tuberculosis are reviewed. In relation to the infection of all organs, 21 cases of tuberculomata of the brain, 4 of the cerebellum and 40 cases of meningitis were found. It was interesting to find out that, while in 607 cases of tuberculous infection there were 3 organs per case involved, when there was tuberculosis of the nervous system the relation was 4 to 1; as a consequence, we can affirm that, when there is a dissemination of tuberculosis, there are more chances of infection of the nervous system. On examining the different organs that were affected on the nervous system cases, we found infection of the lymphatic glands on 18.45%, lungs 15.13% and pleuras 9.25%; in the second place comes the liver with 8.86%, spleen 8.86%, kidneys 6.64%; in a third group the adrenals with 2.58%, prostate 2.58%, peritoneum 2.21% and pericardium 2.21%. In the rest of organs the rate of infection was lesser. From this statistics, we can state that the infection of the ganglia, especially the ones that are located on the hila of the lungs, predisposes to the infection of the nervous system. In relation to age, the maximum of infection was between 10 and 19 years. In 40 cases of tuberculous meningitis, we found miliary tuberculosis in 14 (35%).
