Tenting of the diaphragm (Katten's sign) is a common finding in upper lobe collapse or where there is loss of volume. Twenty-nine patients have been studied, 12 of these prospectively following upper lobectomy. Division of the inferior pulmonary ligament was carried out in these 12 patients. The computed tomography findings confirm that this sign is due to an accessory oblique fissure.
膈肌帐篷征（卡顿征）在上叶肺不张或肺容积减少时较为常见。我们对29例患者进行了研究，其中12例是在上叶肺切除术后进行前瞻性观察。对这12例患者进行了下肺韧带离断术。计算机断层扫描结果证实，该征象是由副斜裂所致。
