Association between cerebrospinal fluid (CSF) and meningeal enhancement (MgE) findings divided between acute and chronic cases

	Acute		Chronic		P value*
	CSF+	CSF−	CSF+	CSF−
MgE+	6	9	3	8	0.42
MgE−	10	12	0	10
P value*	0.04

CSF⁺ = abnormal CSF analysis; CSF⁻ = normal CSF analysis; MgE⁺ = presence of meningeal enhancement; MgE⁻ = absence of meningeal enhancement
