Pulmonary sequestration: Diagnosis with multidetector computed tomography

Pulmonary sequestration is an uncommon disease with non-functioning pulmonary tissue and anomalous systemic blood supply. The diagnosis depends on identification of abnormal systemic vessels. Arteriography, CT, MR and Doppler ultrasound can been used for diagnosis. MDCT is fast, allows high-resolution volumetric imaging that can be obtained during a single breathhold and single-phase contrast injection. Moreover, volumetric helical imaging allows three-dimensional reconstruction of data, which is useful in the demonstration and characterization of the lesions and also showing vascular structures. Herein, a case of pulmonary sequestration diagnosed by MDCT is reported.
