A paraesophageal bronchogenic cyst with esophageal communication

Abstract

Paraesophageal bronchogenic cysts are a rare developmental anomaly of the upper digestive tract. Although often asymptomatic, their growth can cause severe symptoms and complications because of the location. The diagnosis is difficult and is mostly by histopathologic findings after extirpation of the cyst. The authors present a case of a paraesophageal bronchogenic cyst, of typical histologic structure (ciliated epithelium and hyaline cartilage) connected with the esophageal lumen by a narrow canal composed of stratified squamous epithelium. According to the available literature, only three cases of bronchogenic paraesophageal cysts with esophageal communication have been reported.

Cisto broncogênico complicado por mediastinite e empiema contra-lateral

“…This finding would be rare, but not unheard of, in cases of this type of cyst. (7) The case reviewed here is of consequence because it demonstrates that bronchogenic cysts may be atypical in location and presentation, and it reinforces the need for surgical intervention, even when there are no symptoms.…”

A case report of para-esophageal bronchogenic cyst with esophageal communication

“…So whether this represents a post-inflammatory change or a congenital communication remained a matter of conjecture. In 1999 when Knezevic J and his colleagues present a case of a well prepared para-esophageal bronchogenic cyst connected with the esophageal lumen by a narrow canal composed of stratifed squamous epithelium [8]. In this patient, the transition of the ciliated epithelium of the cyst into the stratifed squamous epithelium of the cystic canal serves to emphasize the close anatomic and embryologic relationship between esophagus and the bronchial cystic derivatives [8].…”

Consider the context of their embryologic development from the foregut, as well as on a histologic basis, the presence of an esophageal communication was thought less remarkable.…”

“…For the Pare-esophageal cysts, the patient more likely present symptoms of dysphagia and chest pain due to compression and pleural irritation [1,3,4]. But for the lumen-communicated pare-esophageal cyst, the symptoms may also associated with the penetration of liquid and air through the canal from the esophagus into the cyst [8]. This can explain why our patient present with an irreversible dysphagia and chest pain in his past history.…”

Paraesophageal Bronchogenic Cyst

“…While paraesophageal bronchogenic cysts are uncommon, a paraesophageal bronchogenic cyst that communicates with the oesophagus is rare. Few reports of paraesophageal bronchogenic cysts that communicate with the oesophagus are available in the literature [7,8].…”
