Vertical fissure line in a normal adult.
The major fissure when directed in the sagittal plane is visualized on a frontal roentgenogram. It is reported in infants and children as the vertical fissure line and may occur with cardiomegaly and/or respiratory infection which rotates or partially collapses the lower lobe. Its presence in a normal adult chest is presented. It is believed to represent a congenital positional variant.
