Left Upper Lobe Atelectasis Luftsichel Sign

Left Upper Lobe Atelectasis
55-year-old female with central squamous cell carcinoma of the lung with left upper lobe collapse and hyperinflation of the left lower lobe resulting in a Luftsichel sign. The major fissure is displaced superiorly and anteriorly and the hyperinflated left lower lobe is hyperexpanded and fills the apical space resulting in the hyperlucency in the apex.
