Two simultaneously occurring hypopharyngo-oesophageal diverticula

Abstract

We report a case of two simultaneously occurring hypopharyngeal-oesophageal diverticula. one apparent originating above. the other below the cricopharvngeal muscle. The radiological and clinical findings of tis rare condition are condition are presnted.

Laimer’s Diverticulum, A Rare True Diverticulum Inferior to the Cricopharyngeus: Report of a Case and Review of the Literature

“…Laimer's diverticulum has been documented in three cases in the literature [2][3][4]. In 1993, Boysen reported two large hypopharyngeal diverticula in one patient with an upper diverticulum originating above the cricopharyngeus and a lower diverticulum originating below the cricopharyngeus.…”

“…This diverticulum results from the lack of relaxation of the cricopharyngeus muscle during swallowing, causing a pulsion diverticulum in Killian's triangle between the cricopharyngeus and the inferior pharyngeal constrictor muscles [1]. A much rarer type, Laimer's diverticulum, has been described in three prior case reports [2][3][4] and arises from the posterior upper esophagus, inferior to the cricopharyngeus. We present a case of a patient with a hypopharyngeal posterior true diverticulum inferior to the cricopharyngeus consistent with Laimer's diverticulum.…”

Atypical Pharyngeal Pouch Arising Bilaterally between the Hyoid Bone and Thyroid Cartilage

“…The rarest variant of pharyngeal diverticulum is often referred to as Laimer's or Laimer-Haeckerman's diverticulum. Similar to the Killian-Jamieson diverticulum, it originates between cricopharyngeus and the longitudinal muscle of the oesophagus; however, it is located posteriorly and midline, from the area termed Laimer-Haeckerman's triangle, and is covered only by the circular muscles of the oesophagus [4–6]. The various subtypes of pharyngoesophageal diverticulum are easily distinguishable with radiographic studies [2].…”

“…The various subtypes of pharyngoesophageal diverticulum are easily distinguishable with radiographic studies [2]. There have only been 3 reports of Laimer-Haeckerman's diverticuli thus far [4–6]. …”

Pharyngo-esophageal diverticulum arising from Laimer's triangle

“…A diverticulum is clearly revealed at the C5-6 level (A lateral view, B front view) A B gle, located below the cricopharyngeal muscle, are much rarer. Boysen et al [3] reported a single case of the coexistence of Zenker's and Laimer's diverticula out of more than 1000 reports of hypopharyngo-esophageal diverticula [1,7,10,11]. Various treatment modalities and causes for a pharyngo-esophageal diverticulum have been documented in western countries and the lower incidence of this type of diverticulum in Asian people probably explains why few cases have been reported in Asian countries.…”
