Introduction: Non-occlusive caecal infarction is a rare condition that has been described in association with a variety of clinical entities, generally due to a low-flow state, and has been reported to occur in association with chronic heart disease, open-heart surgery, certain drugs, and haemodialysis. The aim of this article is to describe the presentation, diagnosis and management of this unusual clinical problem.
Case presentation: We report on an 84-year-old female with known chronic heart disease presenting with right lower abdominal quadrant pain, tenderness and leukocytosis. Although initial clinical findings were highly suggestive of acute appendicitis, CT revealed marked circumferential wall thickening of the caecum. Intraoperatively, caecal necrosis was confirmed, while the appendix and the remainder of the intestine appeared normal. There was no evidence of major vascular occlusion or embolization. The right hemicolectomy was performed with ileo-transverse anastomosis. Histopatho-logic analysis demonstrated isolated transmural caecal necrosis with marked infiltration of the caecal wall by numerous bacteria and neutrophils as a consequence of nonocclusive ischaemic colitis. The patient recovered completely and was discharged from the hospital on the tenth postoperative day without any surgical complications.
Conclusion: Partial caecal necrosis should be included in the differential diagnosis of acute right lower quadrant pain, especially in elderly patients with chronic heart disease.
