“…They had also found that one of the right lungs had four pulmonary venous openings, one of the openings found lower down in the pulmonary ligament, the position being similar to the one found in this study [10]. Khedekar and Hattangdi had observed in their study on 25 right lungs that 2 (8%) of them had three veins in the hilum and one (4%) had a single bronchus [8]. Variations in the fissures of the lung may alter the usual presentation of collapse of lung leading to difficulty in the diagnosis.…”

“…With regard to the hilum of the left lungs, no significant variation was observed in the number and arrangement of the structures, in the present study. But many authors have reported variations in the number of bronchi, pulmonary artery and pulmonary vein entering the hilum [6,8,10]. All of 25 right lungs in the present study showed a normal pattern of fissures and lobes.…”

The organs of respiration, a pair of lungs, are present in the thorax one in each side of the mediastinum. The right lung has two fissures -oblique and horizontal, and the left lung has a single oblique fissure. The division of the lung into different lobes by the fissures helps in the relative movement of the lobes with respect to one another, thereby contributing to the uniform expansion of the lung. Variations are seen in the number and pattern of fissures, as well as the number and arrangement of hilar structures. Knowledge of the normal morphology of the lung as well as the common variations are essential prerequisites for radiologists, pulmonologists and surgeons. Materials and methods:The variations in the number of fissures, lobes, and arrangement of hilar structures were studied in the right and left lungs of 25 formalin fixed cadavers at Sree Mookambika Institute of Medical Sciences, Kulasekharam.Results: Left lungs -one lung (4%) had two fissures and three lobes. Hilar structures were normal in number and arrangement. Right lungs -Number and pattern of fissures and lobes were normal in all the specimens. Six lungs (24%) had variations in hilar structures with 4 (16%) of them having a single bronchus, two lungs (8%) having three pulmonary veins and one lung (4%) having the atypical arrangement of hilar structures in which the bronchus and pulmonary artery at the same level. Conclusion:Prior anatomical knowledge and possible variations in the number of fissures, lobes, and arrangement of hilar structures, which may be regionally different and are essential prerequisites for clinicians, radiologists and surgeons.

“…In our study we could find few variations of the fissures of the lungs and hilar structures. Table shows the comparison of previous studies with present study data [5][6][7][8][9]. When compared to the previous studies, we found a higher incidence of Incomplete oblique fissure in left lung.…”

Background: Knowledge of variations in fissures and hilar structures of the lungs is necessary for the appreciation of lobar anatomy and hilar anatomy of lungs. Materials and Methods: Morphological variations of fissures, lobar and hilar structures were studied in 50 formalin fixed lungs belonged to 40-80 years age group. Results: In the present study following observation was made: Right sided lungs had, Incomplete Horizontal fissures in 7 lungs, absent horizontal fissures in 2 lungs, among Hilar structures 2 arteries in 5 lungs, 3 veins in 2 lungs, 1 bronchus in 2 lungs. Left sided lungs had, Incomplete horizontal fissures in 2 lungs, among hilar structures, 1 vein in 2 lungs, 3 vein in 2 lungs and 2 bronchus in 7 lungs. Conclusion: Awareness regarding variations in fissures, lobes and hilar anatomy of the lungs is important clinically while interpreting the radiological images as well as to plan various surgical procedures to avoid postoperative complications.

“…Most frequently noted abnormalities consisted of variable numbers of lung lobes and branches of the pulmonary vasculature. [17][18][19][20][21][22][23][24][25][26][27] Fewer studies depicted anomalies in the pulmonary hilum, and even then, their focus remained on the numerical variations of the entering structures, rather than their topographical relationships. [24][25][26] Given that variability of pulmonary structures is not a rare finding in the patient population, the fact that none of the studies reported abnormal locations of pulmonary arteries and bronchi in the hilum signifies uniqueness of our case.…”

The thoracic cavity contains vital cardiovascular and pulmonary structures. Few congenital anatomical variations in the bronchial tree and pulmonary vasculature have been reported. Understanding such variants is crucial during surgical procedures that involve the thorax. During routine dissection of an 89-year-old male cadaver as part of a first-year anatomy course, an anomaly of the bronchial tree was discovered. The left lung hilum was notable for the pulmonary artery being posterior to the mainstem bronchus. The case report describes normal lung development and anatomy and the significance of this novel variation in which has not been previously described in the literature.
