title: [Unusual clinical forms of extrapleural (epipleural) hematoma on the chest x-ray].
abstract: Two cases of extrapleural hematoma, proven during autopsy, are presented. Plain chest films did not demonstrate the typical signs of an extrapleural mass lesion. The roentgenologic differential diagnosis of a free or partially encapsulated pleural effusion and the pathogenesis of extrapleural hematoma are discussed.
