Causes and risk factors
It is a congenital disorder that is more common in men in a 3:1 ratio.
Which are the symptoms?
Younger patients may present with shortness of breath, cyanosis, and other signs of respiratory failure. In older patients, the disease may be asymptomatic with incidental findings on chest x-ray. Signs of chronic lung infection may be present at the same time. In rare cases, a vascular shunt can lead to heart failure.
How is it diagnosed?
The manifestation of the disease is visible on a chest x-ray. A CT scan of the chest is the exam that provides the most detailed information. In some cases, an MRI can add more detail.
How is it treated?
Treatment is surgical resection. In the case of intralobar sequestration, it may be necessary to remove the entire lung lobe.
