bulging fissure


A radiologic finding of lobar consolidation of the lung, in which the affected portion is expanded, leading to a loss of the relative linearity of the lung fissure as seen on a plain film. A bulging fissure is characteristic of acute exudative pneumonia–e.g., typically caused by Klebsiella pneumoniae, but may also be seen in pneumococcal, plague, and haemophilus pneumonia, tuberculosis, mass lesions, and large abscesses. 

Synonym Sagging fissure sign
