ObjectiveDouble lung point is a rare sign of pneumothorax in clinical practice. In this report I presented an 18-month-old child who presented with bilateral pneumothorax.Data Synthesis And Case PresentationUltrasonography examination revealed conventional lung point sign on the right and double lung point on the left side. Thoracentesis was attempted and closed thoracic drainage was performed on the right side, but no gas was drawn on the left side. Clinical implication of double lung point sign found in chest ultrasonography is that the size of pneumothorax is limited and conservative treatment is enough.ConclusionsTo the best of our knowledge, this is the first case of double lung point identified with ultrasonography in child. The strength of the case is that the double lung point sign is supported by computed tomography (CT). Furthermore, we propose that the presence of double lung point indicates limited pneumothorax and conservative management may well be attempted.
