Background: Schistosomiasis or snail fever is an endemic parasitic infection caused by various trematodes of the genus Schistosoma. People acquire the disease through contact with water containing infected snails. It is one of the most widespread human parasitic infections in tropical and subtropical regions of the world such as Africa, South America, the Middle East, Asia and the Caribbean. In 1996, the World Health Organisation estimated that more than 200 million people living in rural areas are affected by this disease. However, the diagnosis is difficult in low prevalence areas because of a low index of suspicion.
Case Report: Herein, we present a case of a 14-year old boy who had intermittent passage of blood in urine for the past 3 years. Clinical examination and initial investigations did not reveal any abnormality. Bladder schistosomiasis was suspected after contrast-enhanced computed tomography and later confirmed by cystoscopic biopsy.
Conclusions: Bladder schistosomiasis is a prevalent disease in the developing countries, but in non-endemic areas diagnosis may be often missed. The diagnosis should be considered in patients presenting with sporadic episodes of haematuria who have immigrated from or travelled to areas where this disease is endemic.
