A case of bilateral psoas abscess in multiple myeloma patient / 대한내과학회지

ABSTRACT

Psoas abscess is caused by primary or secondary and most commonly results from direct extension of intraabdominal infections. Staphylococcus aureus is the most common organism for psoas abscess secondary to vertebral osteomyelitis. Tuberculosis, malnutrition, alcoholism, diabetes mellitus, bone marrow failure, and steroid use are responsible for compromise in host defense and consequent increase in the relative risk of psoas abscess. We report here a case of bilateral poas abscess developed in a 58 year old patient with relapsed plasmacytoma in pelvic cavity during chemotherapy.
