Background: Actinomycosis is an uncommon, chronic, granulomatous disease that can be mistaken for a malignant tumor. Abdominopelvic actinomycosis constitutes about 20% of all actinomycosis cases and may mimic malignancy, tuberculosis, or other abdominopelvic inflammatory diseases. This condition is more prevalent in women who use an intrauterine device. We report the case of a 38 year old female, known case of type 2 diabetes mellitus with a down 3 year history of right sided abdominal pain and discomfort, weight loss with a previous history of intrauterine device for 5 years she has undergone evaluation for her complaints at multiple times in a peripheral health care centers with colonoscopy and mucosal biopsies and treated for inflammatory bowel disease. CECT Enterogram showed wall thickening involving the IC junction and medial wall of caecum and she undergone laprotomy and right hemicolectomy. Histopathologic evaluation of surgical specimens showed actinomycosis in the caecal wall. The findings were immediately informed to the clinician and advised for a prompt further evaluation and management.
