Actinomycosis of the psoas iliac muscle: concerning a case

ABSTRACT

Actinomycosis are bacterial infections considered non contagious, caused by Actinomyces, gram positive filamentous bacilli, mucuous buccal digestive saprophytes. The abdominal or pelvic locations are rare, and may stimulate a neoplasic affection by causing delicate diagnosis problems. We here report a case of actinomycosis of the right ilio-psoas muscle in a fifty-year old patient with a tumor syndrome of the right iliac fossa, with no abdominal pelvic compression. We did not notice any entrance. The actinomycosis diagnosis was led thanks to anatomo-pathologic exam. The treatment consisted of a tumor resection with betalactamine based antibiotherapy. The pelvic actinomycosis is a rare affection with a difficult diagnosis because of the failure to recognize it as well as its presentation that is similar to a neoplasic process
