====== Parasitic infection ======

A number of parasitic [[infection]]s may involve the [[central nervous system]]. [[Immunosuppression]] (including [[HIV]]) increases susceptibility
((Walker M, Kublin JG, Zunt JR. Parasitic [[central nervous system]] [[infection]]s in immunocompromised [[host]]s: [[malaria]], [[microsporidiosis]], [[leishmaniasis]], and [[African trypanosomiasis]]. Clin Infect Dis. 2006; 42: 115–125)).

CNS parasitic infections include:

[[Schistosomiasis]]

[[Malaria]]

[[African trypanosomiasis]].

[[Balamuthia granulomatous]]

===== Those that potentially involve neurosurgical intervention =====

[[Cysticercosis]]: see [[Neurocysticercosis]].

[[Toxoplasmosis]]: may occur as a congenital [[TORCH infection]], or in the adult usually with [[AIDS]].

[[Toxoplasma gondii]] is an obligate intracellular protozoan that is ubiquitous but does not cause clinical infection except in immunocompromised hosts. Histologic features: [[necrosis]] containing 2–3 nm tachyzoites (cysts)

[[Echinococcus]]

[[Amebiasis]]: ≈ exclusively Naegleria fowleri.
