Abstract

Pulmonary sequestrations (PS) are rare congenital pulmonary malformations, characterized by non-functioning and dysplastic pulmonary tissue, without a normal connection to the tracheobronchial tree and supplied by the systemic arterial circulation. PS typically occur in the lower lobes and the radiologist should consider the possibility of a PS in a patient with persistent or recurrent pneumonia in the lower lobes, especially in children. We hereby present a rare case of bilateral intralobar PS complicated with bilateral pneumonia, in a previously healthy 37-year-old male patient, who was referred to the emergency department by his general practitioner because of persisting dyspnea and fever. The hospital stay was complicated with central nervous aspergillosis due to septic emboli.

Keywords: Bilateral pulmonary sequestration; CNS-aspergillosis; Pneumonia; Pulmonary sequestration; Septic emboli.
