CELLS COMMONLY SEEN IN CEREBROSPINAL FLUID

FIGURE 24–2 Segmented neutrophils (CSF 31000). FIGURE 24–3 Lymphocytes and monocyte (arrow)
(CSF 31000).

COMMENTS: Small numbers of neutrophils,
lymphocytes, and monocytes may be seen in
normal CSF.
Increased numbers of neutrophils are asso-
ciated with bacterial meningitis; early stages
of viral, fungal, and tubercular meningitis;
intracranial hemorrhage; intrathecal injec-
tions; central nervous system (CNS) infarct;
malignancy; or abscess.
Increased numbers of lymphocytes and
monocytes are associated with viral, fungal,
tubercular and bacterial meningitis, and mul-
tiple sclerosis.
