A CASE OF HEMORRAGIC COLITIS INDUCED BY ENTEROHEMORRAGIC E. COLT : O157

Abstract

A 20-year-old woman with diarrhea, abdominal colic pain, fever, and bloody stool was admitted in our clinic four days after onset of symptoms. In the feces culture, Enterohemorragic E. coli : O157 was revealed. Severe edema, hemorrhagic mucosa with ulcer and erosin was observed in the sigmoid colon to the cecum on colonoscopic examination. Severe edematous mucosa showing thumb-printing sign was demonstrated in the barium enema. Those findings were similar to the antibiotics-associated hemorrhagic colitis. The findings of this colitis showed much severe ulceration and erosion than in the associated hemorragic colitis.
