Abstract : Background To describe the clinical features and therapeutic outcomes of a prospective cohort of children with eosinophilic meningoencephalitis. Methods Children admitted with clinical features suggestive of meningitis along with cerebrospinal fluid (CSF) eosinophilia during the period of 14 years (2008 to 2021) were included. Their baseline characteristics, epidemiologic associations, and treatment outcomes were analyzed and compared with the previous studies. Results We identified 25 children (13 males) satisfying the inclusion criteria. The median age at presentation was 3.9 years (range 0.8 to 17 years); 68% were aged less than two years. Fourteen (56%) children had a history of exposure to snails. Most of them presented with fever, headache, irritability, lateral rectus palsy, and early papilledema. Symptoms started three to 42 days (median duration: 14 days) before admission to our center. All children had peripheral eosinophilia, which ranged from 9% to 41%. The mean CSF white blood cell count was 416/mm3 (range 50 to 1245 cells/mm3) with CSF eosinophilia ranging from 11% to 80%. Brain magnetic resonance imaging was done in 24 children and was normal in 15 (62.5%). Leptomeningeal enhancement was seen in two (8.3%) children, and other nonspecific changes were noted in seven (29.1%) children. All children recovered without any neurological deficits with a standard treatment regimen of albendazole and oral steroids. All were asymptomatic at the last follow-up. None of them had any recurrence during the follow-up period. Conclusion We report one of the largest clinical series of children with eosinophilic meningoencephalitis from an endemic area of South India.
