Eosinophilic myelitis is an important cause of transverse myelopathy and has to be considered in an appropriate clinical setting. Eosinophilic myelitis due to parasitic infection should be suspected in cases with cerebrospinal fluid (CSF) eosinophilia along with migratory serpiginous skin lesions and recent travel to endemic areas. We report a case with a 1-month history of fever followed by truncal paresthesias, erythematous creeping skin eruptions, and paraparesis with blood and CSF eosinophilia on a background history of consuming undercooked fish. Magnetic resonance imaging (MRI) spine showed long segment T2 hyperintensities with contrast enhancement. He was tested positive for 24kDa antigenic component of Gnathostoma spinigerum in CSF and serum by immunoblot testing. The patient showed significant improvement with parenteral steroids.
