    Author: Yang CY, Liu HY, Lin HL, Lin JN.
    Journal: J Emerg Med; 2012 Dec; 43(6):980-2. PubMed ID: 21550751.
    Abstract:
    BACKGROUND: Acute appendicitis continues to be a condition at high risk for missed and delayed diagnosis. It characteristically presents with right lower quadrant pain after vague epigastric or periumbilical discomfort. Left-sided appendicitis is an atypical presentation and has been reported rarely. The majority of these cases have been described to be associated with congenital midgut malrotation, situs inversus, or an extremely long appendix. We report a case of left-sided acute appendicitis occurring in a patient with a redundant and hypermobile ascending colon. OBJECTIVES: To alert emergency physicians to an anatomical anomaly that could delay the diagnosis of appendicitis. CASE REPORT: A 50-year-old man presented with fever and left lower abdominal pain. Physical examination revealed local tenderness over the left lower quadrant. Abdominal computed tomography scan revealed a redundant, floating, ascending colon and inflammatory appendix adhering to the descending colon over the left lower abdomen. Exploratory laparotomy was performed and perforated appendicitis with turbid ascites was found during the surgery. Appendectomy was performed and the patient recovered uneventfully. CONCLUSION: This case is presented to increase awareness among emergency physicians of this anatomical variant and atypical presentation of appendicitis.
