Incomplete development or even the absence of the major or minor fissures can lead to confusion in distinguishing adjacent lobes. This report aims to present a rare intraoperative finding of an anatomic malformation of the right lung in a 19-year old male patient with recurrent pneumothorax who underwent a surgical repair. An accessory fissure which was separating the superior segment of the lower lobe from the basal segments gave to the whole lung the unique image of a four-lobed one. A profound knowledge of the accessory fissures even if they are incidentally discovered is of pivotal importance for the thoracic surgeon and leads to optimal operative assessment and strategic planning. Keywords accessory fissure lung deformity intraoperative image Introduction Accessory fissures of the lung represent common variations of lung specimens. Several accessory fissures have been well described in time by the anatomists 1 . Accessory fissures can be described anatomically as clefts of various depth composed by two layers of visceral pleura. They may be complete or incomplete differentiating a part of lung which is termed as an accessory lobe. They are more frequently encountered in fetal and neonatal lung specimens compared to adult ones 1 . Accessory fissures often go unappreciated or misinterpreted on plain x-ray films and computed tomographic CT scans 2 . Case presentation A 19-year old male patient was admitted to our department suffering from recurrent spontaneous .
