Parasitic meningitis, also called eosinophic meningitis, is most commonly caused by cysterci. The larvae stage of tapeworm (pork tapeworm) travels via bloodstream to the brain, causing allergic reactions in this migratory phase, hence term eosinophic. The Centers for Disease Control and Prevention states "Primary amebic meningoencephalitis (PAM) is a very rare form of parasitic meningitis that causes a fatal brain infection. The parasite enters the body through the nose and is caused by the microscopic ameba (a single-celled living organism)."
Planarians are free living and not parasitic. Other classes of their phylum, including flukes and tapeworms, are parasitic when they live inside another organism.
It's called a parasitic relationship.
