Abstract

Fig. 1. Chest multi-detector computer tomography. Maximum intensity projection (MIP) reconstruction on axial plane showing, at presentation, an accessory diaphragm (white arrow) in the lung parenchyma (A). Coronal MIP reconstruction showing accessory diaphragm (white arrow), a systemic artery arising from thoracic aorta to supply the intralobar sequestration in the RLL (right lower lobe) and a phrenic artery from the coeliac trunk (black arrow), progressing to supply the accessory diaphragm (B).
