摘要: The mediastinal lines visible at conventional radiography represent the interfaces between mediastinum and adjacent lung parenchyma. Preservation, obliteration, thickening distortion of these key to detecting localising abnormalities on chest radiographs. learning objectives this review are to: illustrate radiographic anatomy with particular attention lines; describe signs that allow identifi cation diffi cult detect radiographs; fi ndings help localise in anterior, middle or posterior mediastinum. anterior junction line hilum overlay sign, preservation silhouette sign right cardiac border localisation lesions. Widening paratracheal stripe, azygo-oesophageal recess convex aortopulmonary window indicate presence a abnormality. Thickening, disruption paraortic paraspinal obliteration caused by Knowledge normal is crucial identifying subtle can be easily missed radiography. Moreover, approach allows involved compartment radiographs, thereby directing most appropriate further diagnostic workup. Riassunto Le linee mediastiniche rappresentano le superfi ci di contatto tra il mediastino ed parenchima polmonare adiacente. La conservazione, la cancellazione, l’ispessimento o deformazione delle chiave per care e localizzare patologie sul radiogramma del torace. Gli obiettivi diagnostici della nostra sono stati: illustrare l’anatomia radiografi ca con particolare riferimento alle mediastiniche; descrivere i segni che aiutano ad alterazioni cile diagnosi ca; consentono lesione livello anteriore, medio posteriore. cancellazione linea giunzione segno dell’ilo sovrapposto, conservazione
