juxtaphrenic peak sign, also known as diaphragmatic tenting or Kattan sign, refers to the peaked or tented appearance of a hemidiaphragm, which can occur in the setting of ipsilateral lung volume loss, e.g. lobar collapse, post lobectomy. It is caused by the retraction of the diaphragm at an inferior accessory fissure (most common 1), major fissure, or inferior pulmonary ligament. It is commonly seen in left or right upper lobe volume loss but may also be seen in middle lobe collapse
