A 44-year-old white woman was admitted to the Emergency Department with complaints of right lower abdominal pain, nausea and vomiting for 2 days. Significant findings included local rebound tenderness and palpable fullness over the ileocecal region, leukocytosis, lowgrade fever, and ultrasonographic evidence of acute appendicitis. The blood results were as follows: pH was xx with a base excess of XX, sodium was 142 mmol/L; potassium was 3.1 mmol/L; haemoglobin was 129 g/dL; white cell count was 14.8 x 109/L, liver function were normal.\nShe was previously healthy and had no significant past medical history. A provisional diagnosis of acute appendicitis was made. At operation, through a Mc Burney incision, the appendix was found to be normal but a 3 cm gangrenous and perforated ascending colonic diverticulum was found. The patient underwent an appendectomy with isolated diverticulectomy and recovered uneventfully.
