Pharyngo-esophageal diverticulum arising from Laimer's triangle.

Among pharyngo-esophageal diverticula the most frequent type is Zenker's diverticulum, which originates above the cricopharyngeal muscle and below the thyropharyngeal muscle. Laimer's diverticulum, located below the cricopharyngeal muscle, is a much rarer type. We report a case of a 54-year-old woman with a 3-year history of pharyngeal discomfort that was diagnosed as Laimer's diverticulum. To the best of our knowledge, this is only the third such reported case.
