Sail sign of the chest
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.
The thymic sail sign or spinnaker-sail sign is due to elevation of the thymic lobes in the setting of pneumomediastinum.[2]
