Abstract:
This report documents the use of magnetic resonance (MR) in evaluation of intralobar pulmonary sequestration. Because of its distinctive multiplanar capabilities and nonreliance on contrast media to visualize blood vessels, MR can be used to define and characterize the size and course of anomalous arterial feeding vessels. Furthermore, MR can be of value in detecting the presence of mucoid-impacted bronchi within abnormal segments of the lung. It is concluded that in select cases MR may obviate the need for more invasive procedures to establish the diagnosis of pulmonary sequestration.
