Bilateral tuberculous psoas abscess.

The unilateral psoas abscess is a rare disease that is often caused by common germs, including Staphylococcus aureus . Tuberculous origin and bilateral involvement are even rarer, especially in developed countries. It may be primary or secondary to a neighbourhood focus. We report a case of bilateral tuberculous abscess of psoas in an immunocompetent patient secondary to spondylodiscitis.
