B. viral lymphocytic meningitis
C. hematocephalus
D. encephalitis
E. brain abscess


A
This photograph illustrates the typical features of a purulent meningitis. The subarachnoid space contains a creamy purulent exudate, most likely caused by bacteria. Viruses cause a lymphocytic meningitis associated with a serous exudate that does not have the creamy appearance typical of pus. Hematocephalus denotes accumulation of blood in the ventricles. Encephalitis is most often caused by viruses and in its pure form does not manifest with pus in the subarachnoid spaces. Brain abscesses are localized pus-containing cavities or space-occupying masses inside the brain parenchyma.
