Detailed explanation-1: -The luftsichel sign is a clue to the diagnosis of left upper lobe collapse. As the left upper lobe collapses, it moves anteriorly and superiorly to lie against the anterior chest wall, with the hyperexpanded left lower lobe located behind the upper lobe (2) (Fig 2).

Detailed explanation-2: -The luftsichel sign is seen in some cases of left upper lobe collapse and refers to the frontal chest radiographic appearance due to hyperinflation of the superior segment of the left lower lobe interposing itself between the mediastinum and the collapsed left upper lobe.

Detailed explanation-3: -’Luftsichel’ is a German word that means air crescent (luft means air, sichel means sickle). It is seen in upper lobe collapse, more commonly of the left rather than the right upper lobe. The differential diagnosis for the Luftsichel sign includes herniation of the right lung and mediastinal pneumothorax.

Detailed explanation-4: -Atelectasis (at-uh-LEK-tuh-sis) is a complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid. Atelectasis is one of the most common breathing (respiratory) complications after surgery.

Detailed explanation-5: -Trachea deviated to the left (arrow) Right heart border not visible-indicating mediastinal shift to the left. Volume loss of the left hemithorax. ‘Veil-like’ opacification of the left hemithorax obscuring the left heart border-characteristic of left upper lobe collapse. More items
