Subdiaphragmatic Bronchogenic Cysts: A Comprehensive Review of the Literature

Abstract

Bronchogenic cysts are foregut-derived developmental anomalies most commonly encountered in the mediastinum and rarely in the abdomen or retroperitoneally. A comprehensive review of the English-language literature of subdiaphragmatic bronchogenic cysts (sBCs) revealed only 48 reported cases of sBC. Although most cases are incidentally discovered, preoperative differential diagnosis often includes tumors with malignant potential and necessitates surgical resection to obtain a definitive diagnosis. Herein, we describe a case of a 46-year-old female presenting with intermittent left flank pain, upon which computed tomography demonstrated a retroperitoneal mass. Upon resection, histopathology revealed the mass to be a thin-walled cystic mass lined by ciliated columnar cells and cartilage, consistent with a subdiaphragmatic bronchogenic cyst. A comprehensive literature review of sBC was also performed.

Gastric bronchogenic cysts: A case report and literature review

“…The predominant locations include the hilar and middle mediastinal area, whereas extrathoracic and subdiaphragmatic bronchogenic cysts are rare ( 15 ). There are <100 subdiaphragmatic bronchogenic cyst cases reported in the literature ( 17 ), but cases of cysts in the gastric wall are rare. Gastric bronchogenic cysts exhibit a higher prevalence in females (female to male ratio, 21:14), with a median age of development at 43 years old.…”

Quiste broncogénico retroperitoneal en paciente con enfermedad de Crohn

“…A pesar del bajo riesgo de malignización de los quistes broncogénicos, la gran mayoría son benignos y asintomáticos. El tratamiento de elección es la enucleación a través de laparotomía (6)…”

Diagnosis of foregut and tailgut cysts by endosonographically guided fine‐needle aspiration

“…3 Subdiaphragmatic bronchogenic cysts, though, are extremely unusual; fewer than 50 cases have been reported. 4 In contrast to the bronchogenic cyst, alimentary duplication cysts contain digestive epithelium in lieu of respiratory epithelium and do not contain cartilage. Although these may involve the foregut, they are most prevalent in the small intestine.…”
