Bronchopulmonary sequestration presenting as haemoptysis with an aberrant blood supply from the pulmonary artery.

Bronchopulmonary sequestration is a rare condition characterised by the presence of nonfunctional, dysplastic lung tissue. This tissue receives blood supply from the systemic circulation. In this case report, we document an exceptional presentation of a woman in her 50s where bronchopulmonary sequestration in the right upper lung lobe led to haemoptysis. This sequestration received blood supply from a pulmonary artery branch, which is unusual and contrary to the usual systemic circulation. The patient underwent a right upper lobectomy, which confirmed the diagnosis of pulmonary sequestration on histopathology. The unique vascular supply and location of this case challenge conventional diagnostic and management approaches. It emphasises the necessity for meticulous evaluation and consideration of alternative vascular sources in bronchopulmonary sequestration cases.
