  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 ...

  Abstract Epiphrenic diverticulum , a rare pulsion diverticulum of the distal esophagus, represents a clinically significant manifestation of underlying esophageal motility disorders such as achalasia. This article provides a comprehensive, expert-level review integrating radiologic findings, clinical presentation, and surgical management, based on a real-world case of a 72-year-old female patient. Emphasis is placed on multimodal imaging interpretation, pathophysiological mechanisms, and evidence-based therapeutic strategies. The discussion follows a structured format consistent with IEEE biomedical literature standards and incorporates high-yield SEO keywords such as epiphrenic diverticulum imaging , achalasia diagnosis , esophageal diverticulum treatment , and barium esophagogram findings . Keywords Epiphrenic diverticulum, esophageal diverticulum, achalasia, dysphagia, esophagogram, chest X-ray air-fluid level, esophageal motility disorder, laparoscopic diverticulectomy,...

  Abstract Corkscrew esophagus, classically associated with Diffuse Esophageal Spasm (DES), represents a rare but clinically significant esophageal motility disorder characterized by uncoordinated, high-amplitude contractions of the distal esophagus. This condition produces the hallmark radiologic appearance of a “corkscrew” or “rosary bead” esophagus on contrast esophagography. Despite its rarity, corkscrew esophagus remains a critical diagnostic consideration in patients presenting with intermittent dysphagia and non-cardiac chest pain. This column provides a comprehensive, expert-level review of corkscrew esophagus, including pathophysiology, epidemiology, clinical presentation, imaging findings, differential diagnosis, diagnostic modalities, treatment strategies, and prognosis, grounded in the latest global literature. A real-world case is presented with imaging correlation, followed by examination-style questions to reinforce learning. Keywords Corkscrew Esophagus, Diff...

 Introduction Urinary retention is a urological condition characterized by the inability to voluntarily empty the bladder completely.  It represents a significant cause of morbidity across diverse populations and remains a clinical entity of high relevance in both acute and chronic settings.  With the aging global population and the rising prevalence of comorbid conditions such as diabetes mellitus and neurological disorders, urinary retention continues to be a crucial area of research and clinical focus. In this comprehensive column, we will review the pathophysiology, epidemiology, clinical presentation, imaging findings, differential diagnosis, diagnostic strategies, treatment modalities, and prognosis of urinary retention.   The discussion will integrate state-of-the-art imaging features illustrated by clinical cases, including CT and ultrasound, provided in the case review file.  1. Pathophysiology of Urinary Retention Urinary retention occurs whe...
