The oblique fissure of the left lung is known to reach its inferior border. The tongue shaped process below the cardiac notch of the left lung is known as the “lingula”. In the present study, we report a case in which the oblique fissure did not reach the inferior border, rather extended into the anterior border of the left lung, thereby lodging the lingula much above its usual position. Thus, the lingula was not at the extreme lower end of the anterior border but it was above the termination of the oblique fissure, on the anterior border of the left lung. To the best of our knowledge, an anomalous position of the lingula has not been reported in literature. Topographical anatomy of cardiac notch, lingula and the oblique fissures may be important for radiologists interpreting skiagrams and surgeons operating on the lungs.
