The urbanization process of schistosomiasis has been described in the literature. The present report shows and discusses some epidemiological aspects of neuroschistosomiasis that emphasizes this trend. Method: The study was done between July, 2005 and June, 2006, and consisted of spinal cord schistosomiasis carriers at the moment of diagnosis. These patients were evaluated whatever the origin and period of the year that they developed the symptoms. Results: A total of 13 patients were evaluated. Ten cases (76.92%) came from the Metropolitan Region of Recife, while the other zones (Zona da Mata, Agreste e Sertão) contributed with just three cases (23.07%). October, November and December (post rainy period) concentrated the majority of the cases (61.54%). Conclusion: The high spatial and temporal concentration of cases in relation to a recent endemic area for Schistosomiasis suggests that the immunological status may be an important factor for installation of Sschistosomal myelitis.
