Given a reported 100% specificity for the diagnosis of pneumothorax, the lung point has been considered a sign that cannot be mimicked. However, we now present a unique case of the presence of lung point in the absence of pneumothorax in a 75-year-old man admitted after coronary artery bypass graft (Fig. 1).
Fig. 1
a Lung point. The yellow arrow shows where lung sliding was absent. A single B-line, marked by the yellow asterisk, was present in the absence of lung sliding. The green arrow shows where lung sliding was present. b The M-mode of the lung point where the immobility of the affected lung alternates with the movement of the healthy lung which can be observed in the M-mode as stratosphere sign (yellow asterisk) alternating with seashore sign (green asterisk) respectively. c Post-operational chest X-ray showing pleural thickening. d Thoracic CT scan showing pre-existent asbestos-related pleural disease. The red arrows on the CT and X-ray indicate pleural thickening and calcification
