Esophageal intramural pseudodiverticulosis is an unusual condition manifested by tiny flask-shaped outpouchings in the wall of the esophagus. The condition was diagnosed in 21 (0.15%) of 14,350 patients undergoing radiologic examinations of the esophagus at our hospitals. The pseudodiverticula were detected only by single-contrast technique in five of 18 patients (28%) who underwent both single- and double-contrast examinations. Thus, thin, low-density barium seems to enter these structures more readily than the high-density barium used for double-contrast esophagography. While most patients reported in the literature have diffuse or segmental pseudodiverticulosis associated with high esophageal strictures, the majority of our patients (11 [52%] of 21) had isolated involvement of the distal esophagus with 10 or fewer pseudodiverticula in the region of a peptic stricture. Other associated conditions included Candida esophagitis, herpes esophagitis, and squamous cell carcinoma of the esophagus. Our experience suggests that pseudodiverticulosis usually represents a sequela of reflux esophagitis, although the reason that so few patients with esophagitis develop this condition is unclear.
食管壁内假性憩室病是一种罕见疾病，表现为食管壁上微小的烧瓶状憩室。在我院接受食管放射学检查的14350例患者中，有21例（0.15%）被诊断为此病。在18例同时接受单对比和双对比检查的患者中，仅通过单对比技术在5例患者（28%）中检测到假性憩室。因此，稀薄的低密度钡剂似乎比用于双对比食管造影的高密度钡剂更容易进入这些结构。虽然文献报道的大多数患者有与高位食管狭窄相关的弥漫性或节段性假性憩室病，但我们的大多数患者（21例中的11例[52%]）食管远端单独受累，在消化性狭窄区域有10个或更少的假性憩室。其他相关疾病包括念珠菌性食管炎、疱疹性食管炎和食管鳞状细胞癌。我们的经验表明，假性憩室病通常是反流性食管炎的后遗症，尽管食管炎患者中很少有人发展为此病的原因尚不清楚。
