[Cerebral nocardiosis as surprising cause of a convulsive seizure]

Underlying a convulsive seizure of an adult patient many different types of cause can be detected, such as alcohol withdrawal, disturbance of the cerebral circulation, cerebral hemorrhage, brain tumor, metabolic disturbances, drugs or infection. In connection with severe central nervous system infections, such as brain abscesses, convulsive seizures occur in approximately one out of five patients. A patient with brain abscess may be nonfebrile and have normal values of inflammatory markers. The diagnosis is based on contrast-enhanced CT scanning or magnetic resonance imaging of the brain. Even surgical sampling is often necessary. In our patient, a rare nocardia-induced brain abscess turned out to be the cause of recurrent convulsive seizures.
