Esophageal intramural pseudodiverticulosis is an uncommon, idiopathic disorder characterized by multiple small outpouchings protruding from the esophageal lumen. Esophageal intramural pseudodiverticulosis is associated with conditions such as gastroesophageal reflux disease and diabetes mellitus, as well as emergent complications including pneumomediastinum. The most common presenting symptom is dysphagia with associated esophageal stricture formation. While the pathogenesis of EIP has yet to be determined, it is important to bring awareness to this unique disease with distinctive diagnostic findings and treatment options. In this case, we present a 62-year-old woman who suffered from dysphagia, an inability to tolerate a regular diet, and unintentional weight loss for several years prior to her diagnoses. She was diagnosed by esophagram and esophagogastroduodenoscopy to have esophageal intramural pseudodiverticulosis, complicated by severe stricture formation. Following treatment with sequential dilatation and maintenance H2-blocker therapy, she achieved significant symptomatic improvement. This case highlights the importance of accurate identification and treatment of an uncommon cause of dysphagia, esophageal intramural pseudodiverticulosis. Treatment includes dilatational therapy, as successfully demonstrated in our patient. Furthermore, treatment is focused on optimizing medical management, as demonstrated in our patient with the addition of an H2-blocker for GERD, or addressing potentially serious underlying causes, such as carcinoma, with surgery.

食管壁间假性憩室病引起吞咽困难的罕见原因一例报告及文献复习

食管壁内假性憩室病是一种罕见的特发性疾病，其特征是多个小突出物从食管腔突出。食管壁内假性憩室病与胃食管反流病和糖尿病等疾病以及纵隔气肿等突发并发症有关。最常见的症状是吞咽困难并伴有食管狭窄的形成。虽然 EIP 的发病机制尚未确定，但重要的是要通过独特的诊断结果和治疗方案来提高人们对这种独特疾病的认识。在该病例中，我们介绍了一位 62 岁的女性，她在诊断前几年患有吞咽困难、无法忍受常规饮食以及体重意外减轻。经食管造影和食管胃十二指肠镜检查，诊断为食管壁间假性憩室病，并发严重狭窄。经过序贯扩张和 H2 阻滞剂维持治疗后，她的症状得到了显着改善。该病例强调了准确识别和治疗吞咽困难的罕见原因——食管壁内假性憩室病的重要性。治疗包括扩张疗法，正如我们的患者所成功证明的那样。此外，治疗的重点是优化医疗管理，正如我们的患者通过添加 H2 阻滞剂治疗胃食管反流病所证明的那样，或者通过手术解决潜在的严重根本原因，例如癌症。
