Pelebaran mediastinum dalam rontgen thorax pasien dewasa bisa ditentukan bila ukuran hilus mediastinum lebih besar dari 6–8 cm. Pelebaran mediastinum dapat mengindikasikan berbagai keadaan klinis yang disesuaikan dengan temuan anatomis, seperti diseksi aorta, aneurisma aorta, limfoma, atau thymoma.[2,6]
Rongga Mediastinum
Mediastinum adalah rongga di antara paru-paru kanan dan kiri, berisi jantung, aorta, arteri besar, vena besar, trakea, kelenjar timus, saraf, jaringan ikat, serta kelenjar dan pembuluh limfe. Mediastinum terletak diantara tulang sternum dan tulang vertebra torakal secara anterior-posterior.[1,2,9]
