title: Computed tomography of psoas abscesses.
abstract: Nine surgically proven cases of pyogenic psoas abscesses are presented. The most common finding on computed tomography was diffuse enlargement of the psoas with a central low density area corresponding to an abcess cavity. This was noted in seven patients. The anatomy of the psoas muscle and retrofascial area is discussed, as well as the changing etiology and bacteriology of psoas abscesses.
