The authors report the case of a 33-year-old right-handed man who deve
loped a pure classical amnesic syndrome during the course of a probabl
e tuberculous meningitis. This amnesic syndrome occurred 3 months afte
r the onset of the illness, after the patient had stopped the treatmen
t and it regressed completely after the antituberculous treatment had
been recommenced. The neuroradiological investigations suggested that
both the mamillary bodies and the medial temporal lobe regions were in
volved in this amnesic syndrome.
