- no evidence of meningitic or meningoencephalitic involvement
- Evidence of causation demonstrated by at least two of the following:
- headache has developed in temporal relation to onset of the systemic infection or infestation
- headache has significantly worsened in parallel with worsening of the systemic infection or infestation

This is a heterogenous and ill-defined group of systemic infections, most frequently seen in immunosuppressed patients or in specific geographical areas.
The fungi most commonly involved are the pathogenic fungi (Cryptococcus neoformans, Histoplasma capsulatum and Coccidioides immitis) and the opportunistic fungi (Candida species, Aspergillus species and others). Among protozoa, Pneumocystis carinii and Toxoplasma gondii infestations may be associated with headache. Headache has also been reported with the nematode Strongyloides stercoralis.
