OBJECTIVE: Although the radiological features of acute appendicitis are well documented, the value of the plain radiography has not been fully appreciated yet. The present study was aimed at determining the frequency of association between acute appendicitis and a radiological sign characterized as an image of fecal loading in the whole cecum. MATERIALS AND METHODS: Plain abdominal radiographs of 100 consecutive adult patients with acute appendicitis proved by surgery and histology were assessed. The presence of fecal loading characterized by hypotransparency in the whole cecum, and sometimes also in the ascending colon, was observed. RESULTS: The image of fecal loading in the cecum was found in 97% of cases of acute appendicitis, independently of age, gender, skin color or stage of appendicitis. CONCLUSION: The present study suggests that the presence of radiological images of fecal loading in the cecum may be a useful sign for the diagnosis of acute appendicitis.
