Chilaiditi's sign possibly associated with malposition of chest tube placement.

Although diaphragmatic paralysis is a rare recognized complication of chest tube malposition, Chilaiditi's sign occurring as a result of this complication has never been reported in literature to the best of our knowledge. We describe one such case, which had an interesting clinical sequence of events and radiographic findings and suggest that the medial end of the chest tube should be positioned at least 2 cm from the mediastinum on the frontal chest radiograph to avoid these complications.
