Abstract:
We report a case of a neonatal sequestration diagnosed antenatally as a progressive left hydrothorax when ultrasound (US) was done at 30 weeks' gestation for polyhydramnios. Postnatal US and computed tomography failed to demonstrate any lesion; magnetic resonance imaging showed a spherical mass in the left chest adjacent to the left lower lobe. At the age of 4 weeks a thoracotomy was performed and the mass was excised. Pulmonary sequestrations may present with a pleural effusion and polyhydramnios as a part of non-immune hydrops fetalis. In our case hydrops was prevented by insertion of a pleuro-amniotic shunt.

Clinical Manifestations:
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
