Edited by ScholarGen MediAI Team Executive Clinical Summary A 3-year-old girl presented with 3 days of fever and decreased breath sounds over the right anterior chest. Chest AP radiography demonstrated a relatively extensive confluent air-space opacity centered in the right upper lobe , accompanied by mild volume loss of the right lung. Additional patchy air-space opacities were present around the right hilum and lower lung field. The left lung was relatively clear, with no pleural effusion or pneumothorax. The overall imaging and clinical pattern is most consistent with right upper lobe pneumonia with consolidation . The more important radiologic lesson, however, is that consolidation is an imaging pattern, not a microbiologic diagnosis . In a young child, focal consolidation may also reflect atelectasis, aspiration, bronchial obstruction from a foreign body, pulmonary hemorrhage, congenital pulmonary abnormality, or, less commonly, a mass. The presence of volume loss deserves parti...

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...
