[Calcified splenic abscess, colonic fistula and ascites in a chronic carrier of Salmonella typhi].

We report the unusual case of a patient with chronic carriage of Salmonella typhi who presented with partially calcified splenic abscess linked to colic fistula and ascitis. The colic fistula could be secondary to ischemic necrosis by left colon compression due to spleen large abscess. Fistula was evidenced by abdominal computed tomography scan and confirmed by barium enema. The possible etiologies of ascitis are either tuberculosis or ascitic peritonitis secondary to the fistulisation; nevertheless, the role of segmentary portal located hypertension cannot be completely excluded. The splenic abscess was probably due to Salmonella typhi which was only isolated from stool specimens. The calcified splenic abscess was the evidence that the infection had occurred first. In addition, the isolation of Salmonella typhi in stool cultures six months after the subject had returned from the Comores proved the chronic carriage. Treatment by splenectomy and left colectomy was successful in this patient.
