  Introduction Atypical mycobacterial lung infection—more formally known as nontuberculous mycobacterial (NTM) pulmonary disease —has emerged as a critical diagnostic consideration in patients presenting with chronic cough and characteristic CT findings. With increasing global prevalence, especially among elderly women, this condition is now a high-value diagnostic keyword in thoracic radiology, pulmonology, and infectious disease practice.   Case Overview: Chronic Cough in an Elderly Female Patient: 64-year-old female Chief Complaint: Chronic nonproductive cough (months) Imaging: Non-contrast chest CT Imaging Findings Figure 1. Axial Non-Contrast Lung Window Demonstrates bronchiectasis (varicoid and cystic) predominantly in the right middle lobe Associated tree-in-bud opacities , indicating endobronchial spread of infection Peribronchial consolidation noted Figure 2. Lateral Non-Contrast Lung Window Confirms mid-lung predomin...

  Introduction Marfan syndrome is one of the most clinically significant hereditary connective tissue disorders, with profound implications across cardiovascular, ocular, and musculoskeletal systems. In modern clinical practice, medical imaging—especially MRI and ophthalmologic imaging—plays a pivotal role in early diagnosis and long-term monitoring. This column presents a case-based, imaging-centered deep dive into Marfan syndrome, optimized for both clinical professionals and advanced blog readers , integrating radiologic interpretation, pathophysiology, and evidence-based management . Case Overview: Progressive Visual Loss in Marfan Syndrome Figure 1. Axial T2-weighted Orbital MRI Bilateral posterior dislocation of the crystalline lenses into the vitreous cavity is observed. The lenses appear as hypointense oval structures displaced posteriorly, confirming ectopia lentis , a hallmark of Marfan syndrome. Figure 2. Normal Orbital MRI Anatomy Normal anatomical positioning of the ...

https://doi.org/10.1056/NEJMicm1403124 Introduction: Understanding Trichobezoar in Clinical Practice Trichobezoar, commonly referred to as a hair bezoar, is a rare but clinically significant gastrointestinal condition characterized by the accumulation of ingested hair within the stomach and sometimes extending into the small intestine. This condition is strongly associated with psychiatric disorders such as trichotillomania and trichophagia, making it a fascinating intersection between gastroenterology, radiology, and psychiatry.  This column provides a comprehensive, expert-level yet reader-friendly analysis of trichobezoar, integrating real case imaging findings, pathophysiology, and diagnosis. https://doi.org/10.4021/gr2008.11.1287 Case Overview: 18-Year-Old Female with Abdominal Pain and Vomiting An 17-year-old female with a known history of autism and trichotillomania presented with: Persistent vomiting for 48 hours Abdominal pain Normal vital signs and laboratory findings Im...
