Juxtaphrenic peak sign
Pattern seen during radiologic examination
From Wikipedia, the free encyclopedia
Juxtaphrenic peak sign is a radiographic sign seen in lobar collapse or after lobectomy of the lung.[1][2] This sign was first described by Katten and colleagues in 1980, and therefore, it is also called Katten's sign.[3] The juxtaphrenic peak is most commonly caused due to the traction from the inferior accessory fissure.[2][4] The prevalence of the juxtaphrenic peak sign increases gradually during the weeks after lobectomy of the lung.[5]
