IMAGING CHARACTERISTICS OF COMPLICATED ACUTE APPENDICITIS ON MULTI-SLICE COMPUTED TOMOGRAPHY
Main Article Content
Abstract
Objectives: To describe imaging characteristics of complicated acute appendicitis and to determine the most useful findings for diagnosing complicated acute appendicitis on MSCT. Subjects and methods: This is a descriptive cross-sectional, prospective study. From September 2021 to August 2022, 83 patients who presented acute abdominal pain, and were suspected with complicated acute appendicitis clinically underwent MSCT and surgery at Military Hospital 103. Results: The most common finding was a focal defect in enhancing the appendiceal wall (accounting for 37%), extraluminal air and appendicolith were found in only one case (1.4%), abscess in 2.7%, and phlegmon in 11%. Sensitivity and specificity for a focal defect in enhancing the appendiceal wall were 92% and 91.7%, respectively while the remaining findings had high specificity but low sensitivity. Conclusion: Focal defect in enhancing the appendiceal wall is the most useful finding in differentiating complicated acute appendicitis.
