ABSTRACT.

A 67-year-old man presented with headache, middle back pain that radiated to both legs, and paresthesia in the right leg for 1 day. He had eaten raw shrimp 1 week previously. Over the next week after admission, he developed urinary retention and weakness in both legs. The numbness in his right leg expanded to below the umbilicus. Magnetic resonance imaging of the spinal cord showed myelopathy with minimal cord swelling at T9 to the conus medullaris and a hemorrhagic lesion from T10 to T11. A complete blood count on day 28 after the onset of symptoms revealed leukocytosis without eosinophilia and no white blood cells in his cerebrospinal fluid. Results of an immunochromatographic test kit were positive for Angiostrongylus cantonesis but negative for Gnathostoma spinigerum. After a 4-week course of albendazole combined with a tapering dose of dexamethasone, he achieved nearly complete recovery.
