Intralobar bronchopulmonary sequestration: an example of the late onset of this rare congenital pathology

Abstract

Bronchopulmonary sequestration (BPS) refers to a rare congenital lung malformation with a nonventilated dysplastic fragment of parenchyma separated from the main bronchial tree. This segment has a systemic blood supply through aberrant arteries and venous outflow into the systemic venous bed or pulmonary veins and has a common with the rest of the lung (intralobar BPS) or an independent (extralobar BPS) visceral pleura. Purpose of the study is to describe an unusual late onset of right-sided intralobar BPS characterized by a pseudopneumonic course in a patient with concomitant anomalies of the thoracic spine and diaphragm; to discuss the issues of formation, manifestation, diagnosis, differential diagnosis, complications, and treatment of intralobar BPS, and to consider its combination with other developmental anomalies. Conclusion. BLS should be considered in patients with an unusual course of pulmonary anomalies, especially localized in the basal segments of the left (more common) or right (less common) lung and characterized by abnormal blood supply and other malformations.
