Abdominal actinomycosis: barium enema and computed tomography findings.

摘要: A case of abdominal actinomycosis is described in a woman with recurrent right lower pain and low-grade fever without history appendectomy. Past included the use an intrauterine device (IUD) until 10 years before manufestation these symptons. We followed up patient, via diagnostic imaging, for 7 months. On initial barium enema, polypoid lesion was visualized at bottom cecum there constriction sigmoid colon; appendix not seen. Seven months later, poor extension cecum, severe colon, narrowing terminal ileum were also visualized. computed tomography (CT), initially localized only ileocecal region adjacent to colon. After months, had infiltrated anatomic components showed direct infiltration pelvic space. Differential diagnosis difficult, as it obvious whether this abscess due inflammation or appendiceal carcinoma. Laparotomy performed. Macroscopically, limited region, but involved ureter, tubes Fallopian ovary, bladder, psoas muscle, wall. Pathology findings showed, chronic inflammatory tissue evidence actinomycosis. Although previous reports have lack specific disease. When suspected, CT recommended define its extent.
