Abstract
-
Psoas abscess is a rarely encountered disease, and frequently presents non-specific and insidious clinical manifestation, because of which diagnosis and treatment may delay. Staphylococcus aureus has been reported to be the predominant pathogen, whereas Salmonella species have rarely been mentioned as a pathogen. Usually, Salmonella psoas abscess occurs as a complication of a ruptured mycotic aneurysm of the intra-abdominal aorta, or as a consequence of direct extension of an adjacent lumbar spine infection. We report herein an unusual case of primary Salmonella psoas abscess, complicated with deep vein thrombosis and aneurysmal change of the iliac vessels, in a patient with diabetes mellitus who was treated only with antimicrobial therapy. Computed tomography is the most useful and sensitive diagnostic method. A high index of suspicion, early diagnosis, adequate drainage and effective antimicrobial treatment are essential elements in managing the disease.
