Variation in the Lobar Pattern of the Right and Left lungs A Case Report

The anatomical knowledge of the fissures and the lobes of the lung are important for accurate interpretation on CT scans. The right lung classically has two fissures, an oblique and a horizontal, dividing it into three lobes namely upper, middle and lower. Left lungs have one fissure, oblique fissure which divides it into two lobes namely upper and lower lobes. The absence of horizontal fissure in right lung and anomaly of the lobar pattern has been described by many research workers on CT scans. Whereas, there are fewer studies on gross anatomical specimens. In the present case during routine dissection in department of Anatomy, we encountered an anomalous lobar pattern of right lung we report one horizontal and two accessory fissure dividing the right lung into 4 lobes and absence of oblique fissure in right lung. Also the presence of horizontal fissure in the left lungs dividing it into three lobes. The knowledge of anatomical variations of lung fissures is essential for clinicians, surgeons, and for radiologist to recognize various images of related abnormalities because an accessory or anomalous fissure can be mistaken for a lung lesion or an atypical appearance of pleural effusion Dr. Shobha G | Dr. Jeevan Kumar Giri | Dr. Pratikshya Majagaiyan | Dr. Manu Krishnan | Dr. Santosh Singrapu "Variation in the Lobar Pattern of the Right and Left lungs: A Case Report" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-2 | Issue-6 , October 2018, URL: http://www.ijtsrd.com/papers/ijtsrd18755.pdf
