Actinomycosis is a rare infection with Actinomyces israelii mostly seen in the craniofacial region in post pubertal individuals.We present the youngest case of abdominal actinomycosis in a 4-year-old female.Her initial presentation led to a diagnosis consistent with ruptured appendicitis with abscess on computed tomography (CT) OSTEOMOVE EX STRENGTH imaging.Surgical exploration revealed a firm mass involving the cecum, appendix, sigmoid colon and bladder dome suggestive of a soft tissue tumor on frozen section.Final histologic analysis indicated abdominal Picnic Tote actinomycosis in the cecum and sigmoid colon with no evidence of a neoplastic process.
With source control, this patient did well with a very short course of antibiotics.
