Abstract

Recurrent secondary psoas abscess due to Pseudomonas aeruginosa is a relatively rare disease. Diagnosis is often easy through appropriate investigations but the treatment may be difficult, especially in patients with severe underlying conditions. We report a case of recurrent psoas abscess due to P. aeruginosa in same focus after osteosynthesis for kyphoscoliosis. A 65 years old man suffered in post-operative course of recurrent psoas abscess due to P. aeruginosa with relapse intervals of 6 and 2 years. As patient’s condition was a contraindication to the ablation of the osteosynthesis material, we set up a regimen combining percutaneous computed tomography (CT) drainage with antibiotic therapy by ceftazidime after the second relapse. The successful therapeutic regimen established to overcome the patient’s problem is underlined. The treatment of psoas abscess involves the use of appropriate antibiotics in association with percutaneous or surgical drainage. In case of recurrence associated to surgical contraindication, ceftazidime in prolonged administration as performed in our case could be useful.
