Absence of Horizontal fissure with bilateral Inferior accessory fissure and accessory fissure on upper lobe of right lung a rare association of fissure pattern, an incidental finding

Variation in Lung fissure pattern is reported frequently. During routine dissection hours a case of absence of Horizontal fissure in the right lung was observed, which was associated with inferior accessory fissure and accessory fissure on upper lobe. The left lung had an inferior accessory fissure along with the normal oblique fissure. Such fissure patterns are to be taken into account while interpreting a chest radiograph or surgical intervention of any lung lesion.
