What Is a Pulmonary Cyst?

Refers to cystic lesions in the lungs containing gas or liquid gas of various sizes. Divided into congenital and acquired. The former, also known as congenital pulmonary cystic disease, is a congenital malformation of the embryo, including bronchogenic cysts (pulmonary cysts), alveolar cysts, pulmonary lobar emphysema (bulous bullae), cystic adenoma-like deformities, and congenital Cystic bronchiectasis and so on. The latter are secondary to pulmonary infections, such as emphysema bullae, parasitic cysts, and post-infection cysts. Giant cysts can cause dyspnea and fever, cough, and hemoptysis during infection. Rupture of a cyst can cause fluid pneumothorax. X-ray examination can help diagnosis. Needs surgery.

Causes of pulmonary cysts and common diseases

Congenital is caused by congenital developmental defects; congenital is mostly caused by secondary, such as cysts caused by parasitic disease, sequelae cysts caused by infection, and trauma caused by trauma.

Differential diagnosis of pulmonary cyst

1. A single lung cyst in the lower lobe of the right lung. CT scan showed a uniform soft tissue density mass with congested blood vessels visible at the edges.

2. There are multiple cystic calcifications of the lung cyst wall of the right lower lung. Pathology: pulmonary cyst with infection and focal fibrous tissue hyperplasia.

3. Left lung and pulmonary cyst with infection. CT scan showed thick-walled fluid cyst.

4. The left lung and pulmonary cyst were complicated by hemorrhage. CT scan showed a soft tissue density mass with uniform density.

5. Lung cysts in the left lower lobe with infection and inflammatory pseudotumor formation. CT scan showed a soft tissue density mass with uneven density and irregular morphology.

Pulmonary cyst examination

The X-ray showed that the fluid-containing cysts were round and oval-shaped, with uniform density and smooth edges. Polycystic lesions were ring-shaped, honeycomb-shaped shadows, and had fluid level.

Pulmonary cyst treatment principles

Mild cases can be treated symptomatically and conservatively; severe cases can be treated with surgery or maintenance treatment.

Pulmonary cysts are benign lesions, but with cyst enlargement and repeated infections, lung damage can be aggravated and secondary to Aspergillus infection, bleeding, and even canceration. Medical treatment can only improve symptoms, so surgical treatment should be performed as soon as possible. The surgical method depends on the lesion site, size and number of cysts. Local lobectomy was performed on one lobe; multiple lobectomy was performed on the right lobe with multiple lobectomy; multiple cysts involved the whole lung on one side, and pneumonectomy was performed on honeycomb-shaped lesions; cysts were removed on the mediastinum. Attention should be paid to the relationship between the cyst and the adjacent organs, and the cyst wall should be completely removed. If there is a channel with the esophagus or tracheobronch, the channel should be excised and the esophagus or tracheobronchi should be repaired.
