Sail sign of the chest

Sail sign of the chest
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]
