Abscess of the psoas muscle is an uncommon entity. The real incidence is unknown but it seems to be increasing because of the raising use of imaging techniques. The diagnosis can be challenging because of nonspecific symptoms. Fever, hip pain and right iliac fossa tenderness are the classic symptoms; however, it usually has an insidious presentation with fever, abdominal pain, nausea, vomiting, anorexia and other vague manifestations. Staphylococcus aureus is the most common organism in primary psoas abscess. When secondary, cultures are usually mixed. It can cause a variety of infectious syndromes, but it is extremely rare to see psoas abscess due to this organism.
