Apical 'herniation' of the lung is an unusual protrusion of the lung and its pleural coverings through the superior aperture of the thorax. It is supposedly caused by weakness of Sibson's fascia. The phenomenon is an anatomical variation and not a disease entity; however, it must be recognised in order to avoid inappropriate surgery. The condition apparently disappears spontaneously with growth.

肺尖“疝”是肺及其胸膜覆盖物通过胸廓上口的一种异常突出。据推测是由希布森筋膜薄弱引起的。这种现象是一种解剖变异而非疾病实体；然而，为避免不恰当的手术，必须对其加以识别。随着生长，这种情况显然会自行消失。
