title: Group C streptococcal psoas abscess associated with a homolateral hip joint prosthesis infection: a case report.
abstract: An abscess in the psoas muscle is rare and frequently misdiagnosed. A delay in the diagnosis can increase its mortality rate. Some clinical signs can help the clinician but they all are not always present, and not at the same time. We describe in this paper a case report of an association between a psoas abscess and a homolateral hip joint prosthesis infection. It was suspected because of no improvement in clinical state despite treatment of the abscess by antibiotics and drainage, and it required finally other complementary therapeutic solutions. The pathogenic microorganism was a group C streptococcus. We discuss all these points and thereafter we suggest some recommendations for the clinician.
