Bronchopulmonary sequestration is a congenital anomaly in which part of the pulmonary tissue is detached from the normal lung and is supplied by anomalous systemic arteries. The sequestered, aberrant lung tissue does not have normal connections with the tracheobronchial tree or pulmonary arteries. In some patients with anglographic characteristics of this disorder, no sequestration is found at the time of surgery. We present three cases in which systemic arterialization of a portion of lung occurred without actual sequestration. Such cases of pseudosequestration can present a diagnostic challenge preoperatively and should be considered whenever angiographic findings compatible with bronchopulmonary sequestration are found.

    Abstract: Objective: The purpose of this study was to evaluate the feasibility of using multidetector-row CT angiography (CTA) with intra-arterial contrast injection (IA-CTA) to depict the artery of Adamkiewicz (arteria radicularis magna, ARM). Methods: We performed IA-CTA in 27 preoperative...

    We describe the case of a 2-month-old infant with the rare association of aortopulmonary window and anomalous origin of the right coronary artery from the pulmonary artery. The diagnosis was made by angiography and surgical repair was carried on employing the Takeuchi procedure. The angiographic...

    A case of incidentally diagnosed fenestration of the supraclinoid internal carotid artery (ICA) with an associated aneurysm is presented. We present appearances on magnetic resonance angiography, which have not been previously described. Careful interrogation of the data in volume-rendered and...

    Pulmonary sequestration is a congenital lung malformation, defined by dysplastic and non-functioning lung tissue lacking normal tracheobronchial connections and accompanied by an anomalous systemic blood supply. Recognition of anomalous arteries and veins in pulmonary sequestration is paramount...
