title: The extrapleural fat sign: CT characteristics.
abstract: Three cases of medially displaced extrapleural fat are presented. In these cases displacement is secondary to tumor, thoracic wall edema, and hematoma. When significantly displaced, and especially when distorted, the extrapleural fat may present a confusing CT picture. The recognition of this finding may aid in establishing differential diagnosis and staging.
