[Fistula between the urinary bladder and large bowel due to sigmoid tuberculosis]. / Fistulisation vésicale d'une tuberculose sigmoïdienne.

A sigmoid tuberculosis is very rare. We report a case of sigmoid pseudotumoral tuberculosis with a fistulization into the urinary bladder in a 10-year-old girl. The diagnosis of tuberculosis was made by histopathological examination of the surgical specimen after segmental colectomy. Surgery completed by antitubercular chemotherapy gave a good result.
