In tuberculous meningitis, the exudates tends to be most severe:

In tuberculous meningitis, the greatest degree of meningeal involvement and collection of exudates is around the brainstem and at the base of the brain. This is impoant because it can lead either to involvement of the cranial nerves or to obstruction of the basal cisterns and hydrocephalus, both of which are seen commonly in this condition.
