Clinical patterns of tuberculous meningitis have been analyzed for 32
admissions to the bacterial meningitis department of the 2nd Moscow In
fection Hospital in 1983-1991. Early diagnosis of tuberculous meningit
is caused great difficulties because of rare cases of turberculous his
tory, atypical symptoms (an acute onset, in particular), an obscure me
ningeal syndrome, rare neurological symptoms, atypical liquor characte
ristics (frequent neutrophil pleocytosis, a small protein rise, normal
glucose). Secondary bacterial meningitides presented most serious dif
ficulties for differential diagnosis. So did cerebral abscesses and vi
ral meningitis. Antituberculous therapy should be started at first sin
gs of tuberculous nature of meningitis as the disease outcomes are det
ermined to a large extent by early administration of proper treatment.
