A dangerous freshwater contact.

An 8-year-old girl was presented to our department for persistent diarrhoea. A first diagnosis of tuberculosis, along with the result of the chest x-ray scan, had been posed some months before, after a holiday in Brazil, when she started presenting aspecific systemic and gastrointestinal symptoms. The girl was under specific antitubercular treatment when we first saw her. New diagnosis of schistosomiasis was posed by our laboratory tests. Treatment with praziquantel was started and complete resolution of clinical and radiological picture was observed.
