What is the most common cause of eosinophilic meningitis?
Helminthic infections are the most common cause of eosinophilic meningoencephalitis. Though less common, CSF-specific eosinophilia may also be associated with other types of infections, neoplastic diseases, drug use, prosthesis reactions, and miscellaneous idiopathic conditions.
What are the symptoms of eosinophilic meningitis?
The most common symptoms and signs of eosinophilic meningitis caused by A. cantonensis infection include headache, neck stiffness, nausea, vomiting, and paresthesia. Ocular cases with or without meningitis have also been reported. In such cases, motile worms may be observed in eye chambers.
Is eosinophilic meningitis fatal?
Most patients present with a meningitis characterized by eosinophils in the CSF. But, heavy infestations can produce an encephalitis characterized by severe neurological symptoms, coma, and even death.
What conditions may be associated with a findings of eosinophilia in the blood?
Specific diseases and conditions that can result in blood or tissue eosinophilia include:
- Acute myelogenous leukemia (AML)
- Allergies.
- Ascariasis (a roundworm infection)
- Asthma.
- Atopic dermatitis (eczema)
- Cancer.
- Churg-Strauss syndrome.
- Crohn’s disease (a type of inflammatory bowel disease)
What causes eosinophils in CSF?
Although there are several possible causes of eosinophils in the CSF, parasitic infection is the main cause. The three common parasites causing eosinophilic meningitis include Angiostrongylus cantonensis, Gnathostoma spinigerum, and Taenia solium.
Is parasitic meningitis fatal?
Medications to reduce the body’s reaction to the parasite. Treatment for amebic meningitis includes a medication called miltefosine. However, amebic meningitis is typically fatal.
How is parasitic meningitis diagnosed?
Diagnosis. If a doctor suspects meningitis, he or she may collect samples of blood or cerebrospinal fluid. The laboratory looks for evidence of parasitic infection and to rule out other causes. It often is hard to find these parasites in the cerebrospinal fluid or in other parts of the body.
What is human eosinophilic meningitis?
Eosinophilic meningitis (EM) is defined as clinical signs of meningitis associated with the presence of >10 eosinophils/μl cerebrospinal fluid (CSF) and/or ≥10% eosinophilia among CSF leukocytes. EM can be categorized into infectious versus noninfectious.
How long can you have meningitis without knowing?
The first symptoms of viral meningitis typically appear between 3 to 7 days after being exposed to the infection. Symptoms of bacterial meningitis appear and progress quickly – bacterial meningitis is the most dangerous type of meningitis, and the infection progresses the fastest.

Like most blood disorders, eosinophilia is identified on complete blood count (CBC). Eosinophils are one of the white blood cells and are found in the portion of the CBC called the differential.
What parasite causes meningitis?
The three main parasites that cause EM in some infected people are: Angiostrongylus cantonensis (neurologic angiostrongyliasis) Baylisascaris procyonis (baylisascariasis; neural larva migrans) Gnathostoma spinigerum (neurognathostomiasis)

It often is hard to find these parasites in the cerebrospinal fluid or in other parts of the body. In addition to laboratory testing,…
How is Angiostrongylus eosinophilic meningitis (AEM) treated?
Treatment of Angiostrongylus eosinophilic meningitis (AEM) and meningoencephalitis is not well defined and remains controversial.,,– Mild cases resolve spontaneously without specific therapy. More serious cases can be improved with serial lumbar punctures and symptoms shortened with corticosteroid therapy.
What causes eosinophilia in CSF?
It is defined by the presence of 10 or more eosinophils/microL in the cerebrospinal fluid (CSF) or a CSF eosinophilia of at least 10%. The most common cause is invasion of the central nervous system by helminthic parasites, particularly Angiostrongylus cantonensis, but other infections as well as noninfectious conditions may also be associated.
