| Differential diagnosis | left lower lobe collapse |
On a chest X-ray, the sail sign is a radiologic sign that suggests left lower lobe collapse.[1] In children, however, a sail sign could be normal, reflecting the shadow of the thymus.[2]
The thymic sail sign or spinnaker-sail sign is due to elevation of the thymic lobes in the setting of pneumomediastinum.[3]
