A patient with eosinophilic meningitis in Shizuoka Prefecture, Honshu, Japan had nausea, vomiting and headache on admission; laboratory examinations revealed leukocytosis with eosinophilia. Eight days later neck stiffness appeared. Lumbar puncture showed an increase of the initial pressure in association with eosinophilic pleocytosis in the spinal fluid. The possibility of angiostrongylosis was considered because the patient had eaten raw slugs for 4 years as a remedy for lumbago. Although the serum contained cross-reactive antibodies against Toxocara canis, positive reactions to Angiostrongylus cantonensis antigens were observed in all of the immunological tests made. These observations, together with results of epidemiological studies in Honshu carried out by other investigators, suggest that the present case of eosinophilic meningitis may have been caused by A. cantonensis. One previous case has been reported from Honshu Island, Japan.

In the past 50 years, Angiostrongylus cantonensis, the most common cause of eosinophilic meningitis, has spread from Southeast Asia to the South Pacific, Africa, India, the Caribbean, and recently, to Australia and North America, mainly carried by cargo ship rats. Humans are accidental, "dead-end" hosts infected by eating larvae from snails, slugs, or contaminated, uncooked vegetables. These larvae migrate to the brain, spinal cord, and nerve roots, causing eosinophilia in both spinal fluid and peripheral blood. Infected patients present with severe headache, vomiting, paresthesias, weakness, and occasionally visual disturbances and extraocular muscular paralysis. Most patients have a full recovery; however, heavy infections can lead to chronic, disabling disease and even death. There is no proven treatment for this disease. In the authors' experience, corticosteroids have been helpful in severe cases to relieve intracranial pressure as well as neurologic symptoms due to inflammatory responses to migrating and eventually dying worms.

Eosinophilic meningitis (EOM) associated angiostrongyliasis mostly induced by the nematode Angiostrongylus cantonensis, is a common disease with worldwide prevalence. Heavy infections can lead to chronic disabling disease and even death. This study was conducted to shed light on the overall specific IgG antibody response as well as the specific IgG antibody subclass responses in cerebrospinal fluid (CSF) of patients with EOM. Fifteen patients with EOM associated with angiostrongyliasis were included in the study. Sera were screened by immunoblotting for the presence of IgG antibody to the 29 kDaA. cantonensis antigenic polypeptide. CSF was examined by ELISA for the presence of specific IgG and IgG subclass antibodies. Patients presented with headache (100%), neck stiffness (20%), fever (40%), nausea (87%), vomiting (73%), paresthesia (7%), and muscle weakness (7%). Seven of 15 (47%) patients showed peripheral blood eosinophilia and all patients presented with eosinophils in CSF. A sensitivity of 80 % was obtained by combining the diagnostic values of immunoblotting in sera and IgG and IgG subclasses-based ELISA in CSF. The combination of a history of eating raw or semi-cooked infected foods, clinical features, complete blood count, differential cell counts, CSF profiles, and serum and CSF antibodies to A. cantonensis can be used to increase the sensitivity for the diagnosis of human angiostrongyliasis.

Eosinophilic meningitis or encephalitis is a rare disorder and is most commonly caused by Angiostrongylus cantonensis. Humans are accidentally infected when they ingest raw snails or vegetables contaminated with the parasite larvae. Because of the improvement in sanitary food handling practices, the occurrence of A. cantonensis eosinophilic meningitis has been decreasing in Taiwan in recent decades. The common symptoms and signs of eosinophilic meningitis are severe headache, neck stiffness, paresthesia, vomiting, nausea, and fever. Acute urinary retention is a rare presentation. We report a case of A. cantonensis eosinophilic meningitis in an intellectually disabled patient who presented with acute urinary retention without any other meningeal signs. The patient received supportive treatment with corticosteroid therapy and was discharged and received urinary rehabilitation at home.

Angiostrongylus cantonensis is one of the causative agents of eosinophilic meningitis. Humans get infected when they ingest raw or partially cooked snails or monitor lizards (Varanus bengalensis). There is a popular belief that the tongue and the liver of the monitor lizard has aphrodisiac properties. A 20-year-old man was admitted to our hospital with a history of fever, headache and vomiting. His cerebrospinal fluid revealed eosinophilia. He gave a history of the ingestion of a monitor lizard, ten days prior to the onset of the symptoms. So, a diagnosis of eosinophilic meningitis due to Angiostrongylus cantonensis was made. He was treated with oral albendazole and prednisolone. His symptoms improved gradually within two weeks from his admission.

Eosinophilic meningitis, caused by the nematode Angiostrongylus cantonensis, is prevalent in northeastern Thailand, most commonly in adults. Data regarding clinical manifestations of this condition in children is limited and may be different those in adults. A chart review was done on 19 eosinophilic meningitis patients aged less than 15 years in Srinagarind Hospital, Faculty of Medicine, Khon Kaen University, Thailand. Clinical manifestations and outcomes were reported using descriptive statistics. All patients had presented with severe headache. Most patients were males, had fever, nausea or vomiting, stiffness of the neck, and a history of snail ingestion. Six patients had papilledema or cranial nerve palsies. It was shown that the clinical manifestations of eosinophilic meningitis due to A. cantonensis in children are different from those in adult patients. Fever, nausea, vomiting, hepatomegaly, neck stiffness, and cranial nerve palsies were all more common in children than in adults.

Eosinophilic meningitis may be caused by non-infectious and infectious agents. Angiostrongylus cantonensis is the commonest causative agent of eosinophilic meningitis. Rats are the primary hosts of this parasite. Humans get infected by ingestion of raw or inadequately cooked hosts (snails or monitor lizard) or food contaminated with the infective third-stage larvae. A 16-year-old boy was admitted to our hospital with history of fever, headache, and altered sensorium. Magnetic resonance imaging of the brain showed unique findings. Cerebrospinal fluid (CSF) examination showed eosinophilia and the CSF wet mount identified a larva. Patient history revealed ingestion of monitor lizard 2 weeks prior to onset of symptoms. Hence, a diagnosis of eosinophilic meningitis caused by A. cantonensis was made. He was treated with oral albendazole and steroids, resulting in gradual improvement. A. cantonensis as a cause of eosinophilic meningitis is a possibility in patients who present with headache and vomiting after eating raw meat (monitor lizard). To the best of our knowledge, this is a very rare case being reported from India where the larva was identified during the microscopic examination of the CSF.

Rat lungworm, Angiostrongylus cantonensis, is one major cause of human eosinophilic meningitis. This helminth is endemic in Southeast Asia, Pacific Islands, and the Caribbean and has recently expanded to South America. The infection is characterized by an elevated eosinophil count in cerebrospinal fluid. Common symptoms and signs include headache, neck stiffness, paresthesia and nausea/vomiting. The unique history of eating freshwater and land snails or slugs within 2 weeks before onset is helpful for diagnosis. Antihelminthic agents have not shown efficacy in human infection; treatment involves supportive care with management of inflammation and intracranial pressure.
