[Ventriculitis caused by Listeria monocytogenes].

Area of Science:

• Neurology
• Infectious Diseases
• Microbiology

Background:

• Meningitis is a serious infection affecting the membranes surrounding the brain and spinal cord.
• Listeria monocytogenes is a bacterium that can cause severe illness, particularly in vulnerable populations.

Observation:

• A unique case of meningitis caused by Listeria monocytogenes is detailed.
• The infection primarily affected the brain ventricles, leading to ventriculitis.
• The patient underwent thorough clinical and bacteriological analysis.

Findings:

• Listeria monocytogenes was identified as the causative agent of meningitis and ventriculitis.
• The cerebrospinal fluid (CSF) exhibited a distinct greenish-yellow coloration.
• This coloration was noted to resemble the pigmentation of amniotic fluid associated with Listeria monocytogenes.

Implications:

• This case highlights an unusual presentation of Listeria monocytogenes meningitis.
• The characteristic spinal fluid color may serve as a diagnostic clue.
• Further research into the pathogenesis and diagnostic markers of Listeria meningitis is warranted.
