Abstract: The patient was 36 years old female admitted due to periumbilical pain and anorexia since about 24 h prior to hospitalization. She underwent laparotomy with impression of acute appendicitis. Operative finding was Meckel`s diverticulitis, so appendectomy and resection of diverticular bearing Ileum with end to end anastomosis was performed. Post operation course was uneventful and she discharged 5 days later. Pathological study confirmed the diagnosis of Meckel`s diverticulitis due to actinomycosis as the cause of diverticular obstruction. The relatively rare incidence and preoperative diagnosis difficulties make publication of this case worthwhile.
