CHARACTERISTIC ENDOSCOPIC FINDINGS OF ESOPHAGEAL INTRAMURAL PSEUDODIVERTICULOSIS

Abstract

We report the endoscopic findings of a case of esophageal intramural pseudodiverticulosis (EIPD), which was diagnosed using magnifying endoscopy assisted by narrow band imaging (NBI). The patient was a 75-year-old male whose chief complaint was dysphagia combined with weight loss. On upper endoscopy, the lower esophagus was stenotic, and orifices of an EIPD were detected on the oral side of the stricture. On NBI-assisted magnifying endoscopy, the orifices of the EIPD were seen as minute, brownish spots on the mucosa. Each of the spots was surrounded by intraepithelial papillary capillary loops with an eyelash-like appearance. The orifices were difficult to recognize during ordinary endoscopic examination. Magnifying endoscopy is useful for diagnosing EIPD, as it reveals characteristic findings of the condition.
