Ilio-psoas abscess: diagnosis and management

摘要

The triad of fever, limp, and pain in the flank, pelvis or leg often leads to the evaluation of the hip, genitourinary or gastrointestinal system. In the past 6 years, at our hospital, five adolescents and one young adult with these symptoms have had an ilio-psoas abscess, all diagnosed by ultrasonography. Once the diagnosis was established, four patients were treated successfully by percutaneous retroperitoneal drainage guided by ultrasonography 3 or computed tomography 1. Catheter drainage averaged 11 days accompanied by appropriate antibiotics. The remaining two patients had surgical transperitoneal drainage. Growth ofStaphylococcus aureus, from an ilio-psoas abscess indicates that the process is primary in origin. Growth of fecal flora suggests an intra-abdominal process and warrants further investigation. Ilio-psoas abscess can be readily diagnosed by ultrasonography or computed tomography and treated by percutaneous retroperitoneal drainage.
