Pneumothorax Imaging: Practice Essentials, Radiography
In radiology, the deep sulcus sign on a supine chest radiograph is an indirect indicator of a pneumothorax. In a supine film, it appears as a deep, lucent, ipsilateral costophrenic angle within the nondependent portions of the pleural space as opposed to the apex (of the lung) when the patient is upright. The costophrenic angle is abnormally deepened when the pleural air collects latera… WebIn a supine chest x-ray, a deep sulcus sign is diagnostic and this is characterised by a low lateral costophrenic angle on the affected side.
