Introduction: Surgeons must be aware of anatomical variations of the lung during lobar or segmental resections of thelung. Knowledge of these variations prevents misinterpretation of radiological images when these variations occur. Objective: Toinvestigate the incidence of anatomical variations in the pattern of lobes and pulmonary fissures in human cadavers. Method: Seventytwohuman lungs were selected from the collection of cadaver parts of the Department of Anatomy at UFPE. In each cadaveric humanlung was analyzed: antimeria (right and left), the presence of fissures and pulmonary lobes. Results: Of the 72 human lungs selected, 35were right lungs and 37 left lungs. After analyzing the left lungs, there were no anatomical variations in terms of pulmonary lobulationor pulmonary fissures. In the analysis of the right lungs, two variations were observed in different lungs. In the first case, the horizontalcleft was not observed and the lung thus presented only two pulmonary lobes, while in the second case the lung presented an incompletehorizontal cleft. In the other lungs on the right side, anatomical variations were not observed regarding the lobes and pulmonaryfissures. Conclusion: Two anatomical variations were observed in the lobar pattern and pulmonary fissures in the right lung,corresponding to an incidence of 5.4%, and no variations were found in the left lungs.
