Overview
Bronchogenic cyst is a rare benign congenital malformation of the tracheobronchial tree derived from the ventral aspect of the foregut. It most frequently occurs in the middle mediastinum, in the early stages of gestation or in the lungs, at the later stages of gestation. Atypical locations may be explained by its embryologic origin. Patients with bronchogenic cyst may be asymptomatic or present with respiratory distress, increasing stridor, feeding difficulties, chest pain, cough, progressive dysphagia, odynophagia, purulent sputum, dyspnea, anorexia and/orweight loss. Radiologic findings are useful to differentiate bronchogenic cysts from other cysts but may they not always confirm the diagnosis. Diagnosis is confirmed by surgical excision, which is curative, and histological findings of ciliated columnar epithelial lining of the cyst.
Historical Perspective
There is limited information about the historical perspective of bronchogenic cyst.
Classification
Bronchogenic cyst can be classified based on location; pulmonary and extrapulmonary.[1][2]
Pathophysiology
It is thought that bronchogenic cyst is the result of abnormal budding of the ventral [3] portion of the primitive foregut[1][2][4]destined to become the tracheobronchial tree[5] between days 26 - 40 of gestation.
Causes
The cause of bronchogenic cysts is undetermined.
Differentiating Bronchogenic cyst from other Diseases
Differentiating bronchogenic cyst from lung abcess, thymic cyst, and esophageal duplication cysts.
Bronchogenic cyst epidemiology and demographics|Epidemiology and Demographics
There is no racial predilection to bronchogenic cyst. Bronchogenic cyst is slightly more prevalent in men and often remain undetected till the third or fourth decade of life.[6][7]
Risk factors
There are no established risk factors for bronchogenic cyst.
Screening
There is insufficient evidence to recommend routine screening for bronchogenic cyst as it is usually an incidental finding.
