Bronchopulmonary sequestration: radiologic findings.

Bronchopulmonary sequestration (BPS) is a nonfunctioning bronchopulmonary tissue that is separate from the tracheobronchial tree and receives arterial blood from the systemic circulation. BPS has a wide spectrum of imaging findings. Surgery is generally indicated for the treatment of BPS. It is important to demonstrate the arterial supply and venous drainage of the sequestered segment preoperatively. Today, with the help of noninvasive imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI), preoperative diagnosis of BPS can be made easily, so, invasive techniques such as angiography are not required frequently. In this report, radiological findings of BPS were retrospectively reviewed.
