Eosinophilic meningitis

Eosinophilic meningitis is a form of meningitis characterized by an increased presence of eosinophils, a type of white blood cell, in the cerebrospinal fluid. It is often caused by parasitic infections, but can also be caused by certain medications or illnesses.

Causes

The most common cause of eosinophilic meningitis is infection with the rat lungworm, Angiostrongylus cantonensis. Other parasites, such as Gnathostoma spinigerum and Toxocara canis, can also cause this condition. In rare cases, eosinophilic meningitis can be caused by certain medications or illnesses.

Symptoms

Symptoms of eosinophilic meningitis can include headache, nausea, vomiting, fever, and stiff neck. In severe cases, it can lead to paralysis or coma.

Diagnosis

Diagnosis of eosinophilic meningitis is typically made by analyzing a sample of cerebrospinal fluid. The presence of eosinophils in the fluid is a key indicator of the condition.

Treatment

Treatment for eosinophilic meningitis typically involves medications to kill the parasites causing the infection. In some cases, steroids may also be used to reduce inflammation.
