The lungs are paired, soft and spongy organs of respiration present in the greater part of thoracic cavity on either side of mediastinum resting ondiaphragm. The right lung is typically divided into three lobes namely superior, middle and inferior by the oblique and horizontal ssures. The leftlung is divided into superior and inferior lobes by a single deep oblique ssure. The ssures act as a plane of cleavage covered by extensions ofpulmonary pleura that helps in expansion of lungs during respiration. During the routine dissection of thoracic region of human cadaver, right lungwith accessory ssures and distinctive lobar pattern was observed. The right lung was divided into ve disproportionate lobes by four ssures. Theleft lung had normal anatomy without any variation in this case. The variations in the ssures and lobar pattern of lungs are not uncommon and aredue to altered developmental process during intrauterine life. The anatomical knowledge of these variations is important for clinicians prior toperforming any pulmonary surgical procedures and to prevent postoperative complications.
