A Rare Case of Pancolonic Ischemia Complicated by Fusobacterium Necrophorum Bacteremia: A Review of Colonic Ischemia for Internists

The varied clinical presentation and objective findings associated with colonic ischemia (CI) overlap with multiple disease processes. A high index of suspicion is critical for timely diagnosis and prognostication to avoid delays in treatment. We present a case that highlights the challenges of diagnosing CI and the high morbidity associated with severe disease. Case report: A sixty-four-year-old female presented to our community hospital with acute onset abdominal pain, nausea, and diarrhea, complicated by septic shock. She was initially given a diagnosis of infectious colitis until a colonoscopy was performed revealing extensive pancolonic ulcerations. Histopathological features on biopsy were most consistent with colonic ischemia. Blood cultures grew Fusobacterium Necrophorum. Surgery was avoided due to the high morbidity and mortality of performing a total colectomy and ileostomy. The patient continued to struggle with abdominal pain, diarrhea, and hematochezia, consistent with continuous CI, leading to recurrent hospitalizations.
