Meningitis


 

Meningitis is inflammation of the membranes (meninges) covering the brain and the spinal cord. Although the most common causes are infection (bacterial, viral, fungal or parasitic), chemical agents and even tumor cells may cause meningitis. Encephalitis and brain abscess can complicate infective meningitis.

Pathology

Histopathology: Purulent (suppurative) leptomeningitis is a diffuse purulent inflammation. The leptomeninges (arachnoida and piamater) contain purulent exudate (pus): leukocytes (neutrophils), fibrin, germs, proteins, necrotic debris. Blood vessels in the subarachnoidian space and those intracerebral are congested and neutrophil margination is present. Photo at: Atlas of Pathology
