History A 22 year-old male paralegal in the military presented with double and blurred vision. One month ago, he had traveled to Hawai'i for a wedding. Two weeks ago, he had been evaluated for an acute onset of fever, headache, emesis, light sensitivity and neck stiffness.
Disease/Diagnosis Eosinophilic Meningitis secondary to Angiostrongylus cantonensis. Angiostrongylus cantonensis is also known as the "Rat Lungworm" and was first found in the lungs of rats in South China. The nematode larvae live in the pulmonary veins of their definitive host, the rat, and are perpetuated by snails, which serve as a secondary host. It is endemic in Southeast Asia, the Pacific Basin, the Caribbean, and Hawai'i. Humans become infected by eating undercooked snails, freshwater shrimp, frogs, or unwashed produce contaminated by one of these hosts. The larvae migrate to the central nervous system and the induced inflammatory response creates the manifestations typically seen in humans, including meningitis, cranial nerve abnormalities, ataxia, encephalitis, and increased intracranial pressure. The larvae are presumed to die before reaching the lungs. Treatment generally includes high- dose systemic corticosteroids. Albendazole can be used in combination with steroids, but there is some concern that the rapid death of the larvae from the anthelmintic can worsen the inflammatory response.
