Background: To establish the value of saline-filled appendiceal ultrasonography in the diagnosis of clinically equivocal acute appendicitis. Methods: Saline-filled ultrasonography was performed in 43 patients with an equivocal clinical diagnosis of acute appendicitis. Results: Sonography diagnosed 31 of 32 patients without acute appendicitis (97%). A normal appendix was visualized in 15 patients (47%), and we identified a normal appendix in 15 of 22 patients (68%) in whom the colon was cleansed with Golytely®. Sonography diagnosed 10 of 11 patients with acute appendicitis (91%). In three of 10 patients, the findings corresponded to sonographic pitfalls. Conclusion: Saline-filled appendiceal ultrasonography enables the detection of a normal appendix and may overcome sonographic pitfalls in acute appendicitis.
