Abstract
A 67-year-old woman admitted with a chief complaint of fever and left lower abdominal pain. Abdominal enhanced CT demonstrated an inhomogenous density mass in left iliac lesion. Six days on admission, she suddenly had bloody stool. Colonoscopic findings showed the edematous and easy-bleeding mucosa with multiple erosions and longitudinal ulcers in the sigmoid to descending colon. Histological findings of uterine tube revealed the infiltration of inflammatory cells mainly including neutrophils and the proliferation of fibrosis due to pyosalpinx. Colonoscopic findings after surgical treatment showed deformities of the internal wall and normal mucosa in the sigmoid to descending colon. It is rare that pyosalpinx was complicated with ischemic colitis, which would be precious to discuss the pathogenesis.
