In this post, I will delve into the fascinating finding—the Inferior Accessory Fissure of the Lung—a structure often discovered during a CT scan for a patient presenting with chest pain. This anatomical structure is a normal variant that can often be mistaken for atelectasis or scarring. This column aims to go beyond simple information, providing a comprehensive overview based on world-class expert knowledge and current literature. We will cover the Pathophysiology, Epidemiology, Clinical presentation, Imaging features, Differential diagnosis, Treatment, and Prognosis of the Inferior Accessory Fissure.  👨‍⚕️ Case Presentation: A 56-Year-Old Male Complaining of Chest Pain Patient Information : Age : 56 years Gender : Male Chief Complaint : Chest pain The patient underwent a Chest CT scan due to chest pain , which revealed the Inferior Accessory Fissure of the Lung , a normal variant . The findings also included a Right middle lobe atelectatic band . [Fig...

  Introduction to the Duplex Collecting System Kidney (DCSK) The Duplex Collecting System Kidney (DCSK) , often simply referred to as a Duplex Kidney or Duplex Collecting System , represents the most common congenital anomaly of the upper urinary tract. This condition is characterized by a kidney that is drained by two ureters instead of the typical single ureter. While some individuals with this anomaly may remain asymptomatic throughout their lives , others can face significant urological complications, making a thorough understanding of its pathophysiology, clinical presentation, and imaging features essential for medical professionals. 🔬 Pathophysiology and Embryology The embryological origin of the DCSK lies in an abnormal budding or division of the ureteral bud . The ureteral bud typically arises from the distal portion of the mesonephric duct and grows towards the metanephros to form the renal pelvis and the ureter. Classification of Duplex Systems Duplex...
