Eosinophilic meningitis or meningoencephalitis is a disease commonly seen in Taiwan, especially in children during the summer rainy season. Most of the cases reported in other countries were adults and their clinical manifestations were different from children. Studies on special clinical characteristics among 87 children in Taiwan were performed. Thirty-eight (43.7%) were male and 49 (56.3%) females, and 88.5% could be traced to a history of contact with the intermediate host, the giant African snail, Achatina fulica, which plays a major role in transmission. The incubation period (average: 13.0 days) was shorter in children than in adults (average: 16.5 days). Near thirty percent (28.7%) of the total cases, the clinical form was meningoencephalitis, which was higher than in adult cases seen in Thailand (5%). The most common clinical symptom was fever (92.0%), followed by vomiting and headache. The percentages of sixth and seventh cranial neuropathy associated with the disease were 17.2% and 11.5% respectively. Ophthalmologic fundoscopy showed that 23.0% with papilledema which was significantly higher than seen in adults (12%) in Thailand. Most of the cases in this study had peripheral leukocytosis (above 10,000/mm3) and eosinophilia (above 10%); the percentages were 83.9% and 85.1%, respectively. The worm recovery rate from cerebrospinal fluid by lumbar puncture of 87 cases was 43.7%; 141 worms were collected from one female patient using a pumping method. In the recent 3 years, levamisole was used clinically with good result.

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.

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.
