Rib paralleled by the horizontal fissure of the right lung?

Explanation:
The horizontal fissure of the right lung runs at about the level of the 4th costal cartilage anteriorly, effectively running parallel to the 4th rib. This fissure separates the superior from the middle lobe, and its anterior landmark sits at the level of the 4th rib, making the fourth rib the one that parallels it.
