Atelectasis left upper lobe, Case 2

Zoom Notes

Lateral radiograph
Follow-up radiograph


This radiograph shows increased density of the left hemithorax obscuring the left heart border. Note that the opacification extends from the upper portion of the thorax to at least the hilar level. Loss of the cardiac boundary indicates that the heart and the infiltrated collapsed left upper lobe (including the lingula) are immediately adjacent and therefore no distinct left boundary of the heart is defined.
