[Different manifestations of the cerebral nocardiosis].

Nocardial infections affect mainly the respiratory tract but also can attack the CNS. Clinical experience with cerebral nocardiosis is very limited. We present two patients with very different cerebral affections due to nocardiosis. Cerebral nocardial infections can cause both multiple small abscesses and single large abscesses in the human brain. Despite the rare incidence of cerebral nocardiosis, it is an important differential diagnosis of expansive processes and abscesses in the CNS.
