Increased Intracranial Pressure in the Setting of Enterovirus and Other Viral Meningitides

Table 2

Results of lumbar puncture and cerebrospinal fluid testing.

Patient	Opening pressure; (cm H2O)	CSF WBC; (cells/µL)	CSF lymphocytes; (%)	CSF protein; (mg/dL)	Positive microbial studies	Negative microbial studies
1	50	270	88	65	—	EV, Cr, AFB, Fung
2	22	108	71	40	Enterovirus PCR	—
3	>55	13	89	54	—	EV, Cr, AFB, Ly,; Bartonella
4	43	190	60	42	—	EV
5	32	260	93	64	Lyme titer elevated; immunoblot negative	EV
6	21	30	97	30	—	EV, Ly
7	26	13	91	19	—	HSV, viral culture

All patients had a negative CSF bacterial culture in addition to the studies listed.
CSF = cerebrospinal fluid; WBC = white blood cells; EV = Enterovirus PCR; Cr = cryptococcal antigen testing; AFB = culture for acid fast bacilli; Fung = fungal culture; HSV = herpes simplex virus PCR; Ly = Lyme titers.
