Psoas abscess is a rare infectious disease with nonspecific clinical presentation that frequently causes a diagnostic difficulty. Its insidious onset and occult characteristics can cause diagnostic delays. It is classified as primary or secondary. Staphylococcus aureus is the most commonly causative pathogen in primary psoas abscess. Secondary psoas abscess usually occurs as a result of underlying diseases. A high index of clinical suspicion, the past and recent history of the patient, and imaging studies can be helpful in diagnosing the disease. The delay of the treatment is related with high morbidity and mortality rates. In this paper, 54-year-old patient with severe hip pain having an abscess in the psoas muscle due to metastatic cervical carcinoma is presented.
