Abscess of Psoas in Children at Gabriel Toure Chu: about 31 Cases

Introduction: A psoas abscess is a purulent collection in the psoas muscle compartment. The clinical diagnosis of psoas abscesses is difficult due to the misleading clinical presentation and poor and/or unspecific symptomatology. The etiologies are dominated by digestive and bone causes. The treatment of abscesses is based on antibiotic therapy which may or may not be associated with a puncture, percutaneous or surgical drainage. The prognosis depends on how early treatment is received and is generally favorable. We carried out this work with the objectives of studying the clinical and therapeutic aspect of psoas abscess.
