Accessory Lobes and Fissures in Both the Lungs - An Original Cadaveric Case Report

The lungs are a pair of spongy, air-filled organs situated in the thoracic cavity. The right lung normally presents three lobes and two fissures and the left lung presents two lobes and one fissure. The fissures allow greater distention of the lobes during respiratory movements. Many variations have been reported regarding the number of lobes and fissures. Here we report a case of accessory lobes and fissures seen in both right and left lungs in a single male cadaver. The presence of accessory lobes and fissures were noted during routine cadaveric dissection of a middle aged person in the department of Anatomy, Believers church medical college, Thiruvalla. Knowledge and awareness regarding anatomical variations in the lobes and fissures of lungs is essential for surgeons to avoid complications during surgeries like segmental or lobar resection of lungs. It is even important for radiologists to correctly diagnose the accessory fissures and lobes during radiological imaging techniques.
