Purpose: Intrabdominal actinomycosis is difficult to diagnose preoperatively. This chronic infection has a propensity to mimic many other diseases and may present with a wide variety of symptoms. The aim of this study was to evaluate the characteristic clinical features with review of the literature. Materials and Methods: We retrospectively analyzed 22 patients with intrabdominal actinomycosis between January 2000 and January 2006. Results: There were two men and 20 women with a mean age of 42.8 years (range, 24 - 69). Twelve patients presented with masses or abdominal pain, whereas 3 patients presented with acute appendicitis. The rate of performing an emergency surgery was 50% due to symptoms of peritonitis. The mean size of tumor was 5.5 cm (range, 2.5 - 11.0). Sixty percent (n = 12) of female patients had intrauterine device (IUD). The average time to definite diagnosis was 10.6 days. Conclusion: Intrabdominal abdominal actinomycosis must first be suspected in any women with a history of current or recent IUD use who presents abdominal pain. If recognized preoperatively, a limited surgical procedure, may spare the patient from an extensive operation.
