title: [Psoas abscess: diagnostic dilemma in childhood].
abstract: A series of 16 children diagnosed as having a psoas abscess or deep iliac lymphadenitis seen over a 25-year period (1970-1994) is presented. 10 were treated conservatively while 5 were drained surgically and 1 percutaneously under imaging guidance. The presenting signs and symptoms may mimic the frequently seen entities, acute appendicitis and acute hip arthritis. Lower abdominal and inguinal pain, limp, fever and increased white count are common in all of these conditions. Accurate differential diagnosis is necessary to avoid unnecessary surgery due to a wrong diagnosis. Ultrasonography is preferred for diagnosis. Antibiotic therapy should be instituted immediately, aimed primarily at Staphylococcus aureus, the most common causative agent, although other organisms may be implicated. When a psoas abscess has been diagnosed, surgery and drainage are indicated. One of the preferred approaches is percutaneous drainage under imaging guidance. Convalescence is usually rapid and without late sequelae.
