Overview
Parasitic meningitis caused by Paragonimus mexicanus involves cerebral hemorrhagic lesions characterized by eosinophilic infiltration, giant cell granulomas, and Charcot-Leyden crystals, often with extrapulmonary manifestations 1.Diagnosis
Clinical Presentation: Hemorrhagic cerebral lesions, eosinophilic pericarditis, and multi-organ involvement (liver, lungs) 1.
Imaging: CT or MRI showing well-circumscribed hemorrhagic lesions in brain hemispheres 1.
Microscopy: Histopathological examination revealing eosinophilic infiltration, giant cells, and Charcot-Leyden crystals 1.
Egg Detection: Demonstration of Paragonimus eggs in tissue samples (brain, pericardium, liver, lungs) via serial sections 1.Management
Surgical Intervention: Surgical evacuation of hemorrhagic cerebral lesions may be curative in some cases 1.
Supportive Care: Management of complications including respiratory and hepatic involvement 1.
Antiparasitic Therapy: Specific antiparasitic drugs not detailed in the abstract; empirical treatment with praziquantel or triclabendazole may be considered based on Paragonimus species 1.Special Populations
Pediatrics: No specific data provided 1.
Elderly: No specific data provided 1.
Comorbidities: Presence of extrapulmonary involvement (liver, lungs) may complicate management 1.Key Recommendations
Perform histopathological examination and egg detection in tissue samples for definitive diagnosis (Evidence: Weak) 1.
Consider surgical evacuation for symptomatic hemorrhagic cerebral lesions (Evidence: Weak) 1.
Manage extrapulmonary manifestations alongside central nervous system involvement (Evidence: Expert opinion) 1.References
