| Summary: | Angiostrongylus cantonensis (AC) is a parasite that occasionally infects humans, causing eosinophilic meningitis (EM). In this study, we identified two adult males with severe angiostrongyliasis being treated at the ICU. Both presented with mental and behavioral abnormalities and were initially treated for psychiatric disorders before showing symptoms like cough, fever, and altered consciousness. Patient 1, a homeless individual, presented with elevated eosinophil levels and typical meningitis symptoms, prompting an early diagnosis of EM that was later confirmed via next-generation sequencing (NGS) of the cerebrospinal fluid. Patient 2, who had schizophrenia as a pre-existing condition, did not exhibit the typical signs of meningitis but was nonetheless detected via NGS. Both patients responded well to corticosteroids and anthelmintics. A review of case reports underscores heightened infection risks among children with pica and vulnerable adults, including those with mental disorders or homelessness. The use of NGS is effective for the early diagnosis and treatment of severe angiostrongyliasis, especially in those with atypical symptoms. |
