  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,...
