Abstract

The authors report an unusual case of segmental lung torsion detected at CT pulmonary angiography in a patient with dyspnea. This case highlights the importance for clinicians and radiologists to consider and be familiar with the diagnosis of lung torsion, a rare and potentially life-threatening pathologic condition that can be successfully treated with emergent surgery if detected early. Keywords: CT, CT Angiography, Pulmonary, Thorax, Lung, Emergency Radiology Supplemental material is available for this article. © RSNA, 2023.

(A) Chest radiograph and (B–D) corresponding reconstructed CT pulmonary angiography images in coronal (B, lung window; C, mediastinal window) and axial (D, maximum intensity projection) views 1 week later demonstrate deterioration with torsion of the medial basal segment (black arrows) of the right lower lobe. Note the presence of the antler sign (white arrow).
