Case contributed by Dr Charlie Chia-Tsong Hsu

Presentation

45 years old male presenting with shortness of breath. Smoker.

Patient Data

Age: 45
Gender: Male

Frontal (figure 1 and 2) and lateral chest (figure 3 and 4) radiographs demonstrate increased opacity in the left mid and upper zone with associated lucency surrounding the aortic arch/kunckle; Luftsichel sign (dotted red line). The lateral projection shows anterior displacement of the oblique fissure (red arrows). The left hilum and hemidiaphragm are elevated compatible with volume loss.   There is also an additional density in the left hilum with a convex and well defined lateral margin (yellow star). Overall imaging appearance is classic for left upper lobe collapse secondary to left hilar mass concerning for central lung malignancy.

18F-FDG PET/CT confirms the presence of left upper lobe collapse secondary to an FDG avid left hilar mass causing bronchial obstruction/compression. Endobronchial biopsy of this lesion confirms the diagnosis of squamous cell carcinoma.
