Post-mediastinitis aneurysm. Fatal, false aneurysm complicating a mediastinitis following an EBUS procedure. EBUS had been performed in the context of a suspicion of stage IV lung cancer. Contrast-enhanced CT was performed 35 days after EBUS because the patient complained of chest pain. Successive axial CT images (a–c) show a diffuse infiltration of the mediastinal fat with a false aneurysm (arrow) that developed on the right side of the aortic arch. Coronal reformation shows the cranio-caudal extent of the false aneurysm (arrow) (d). A pericardial effusion is present
