[Neurolisteriosis with acute myelitis].

Listeriosis is a bacterial infection with Listeria monocytogenes mostly affecting immunocompromised patients. In every fourth case, the CNS is involved, usually as meningoencephalitis. This case report of an immunocompetent woman represents the first one of neurolisteriosis initially presenting as cervical myelitis and progressing to supratentorial areas of the brain. Diagnosis was based on universal polymerase chain reaction from a cortical brain biopsy, followed by sequencing of the amplified rDNA gene. Under antibiotic treatment with gentamycin and ampicillin, the patient slowly recovered and has been improving ever since.
