From: Poor echocardiographic view can be a sign of the development of thoracic pneumatosis
Representative X-ray images of a patient (an 8-month-old female with weight 5.7 kg and height 60 cm) [5]. On day X, good echocardiographic imaging was obtained; however, the image quality was slightly reduced than the day before. There was no remarkable change suggesting pneumatosis on the X-ray image. On day X + 1, good echocardiographic imaging was not obtained. Taking a closer look at the X-ray image, subcutaneous emphysema (asterisks) is observed around the neck. We overlooked this sign because we were distracted by the change of the X-ray image of the left lung field. On day X + 2, the patient developed severe pneumatosis. The right-side X-ray image shows extensive subcutaneous emphysema (asterisks) and pneumothorax (arrows)
