Bronchogenic cyst
Bronchogenic cyst
Bronchogenic cysts (pronunciation: bron-ko-gen-ic sists) are congenital malformations that occur due to abnormal development of the tracheobronchial tree in the embryonic period. They are typically lined by respiratory epithelium and can be filled with fluid or air.
Etymology
The term "bronchogenic" is derived from the Greek words "bronchos" meaning windpipe and "genesis" meaning origin or formation. The term "cyst" comes from the Greek "kystis" meaning bladder or sac.
Classification
Bronchogenic cysts can be classified into two types based on their location: intrapulmonary and extrapulmonary. Intrapulmonary bronchogenic cysts are located within the lung parenchyma, while extrapulmonary bronchogenic cysts are found outside the lung, usually in the mediastinum.
Symptoms
Symptoms of bronchogenic cysts can vary depending on their size and location. They may be asymptomatic or cause symptoms such as cough, chest pain, dyspnea, or recurrent respiratory infections.
Diagnosis
Diagnosis of bronchogenic cysts is typically made through imaging studies such as Computed Tomography (CT) scan or Magnetic Resonance Imaging (MRI). Histopathological examination of the cyst can confirm the diagnosis.
Treatment
Treatment of bronchogenic cysts usually involves surgical removal, especially if the cyst is causing symptoms or complications. The surgical approach may vary depending on the location and size of the cyst.
