title: The target sign: a new radiologic sign of septic pulmonary emboli.
abstract: A new radiographic sign consisting of a pulmonary density suspended in a thin-walled cystic area is described in five patients with hematogenously disseminated infection. A pathogenetic mechanism is suggested to account for this "target sign." The relationship of these findings to pulmonary pneumatoceles is also discussed.
