Near-fatal haemoptysis as presentation of a giant intralobar pulmonary sequestration

A 50-year-old female with no prior respiratory disease or symptoms presented with massive haemoptysis and respiratory failure. Multidetector computed tomographic angiography demonstrated an aberrant artery supplying a lobulated mass occupying two-thirds of the right chest (fig. 1a and b). Aortography confirmed a large aberrant systemic artery originating from the supra-diaphragmatic aorta (fig. 1c), with drainage into the pulmonary veins (fig. 1d). Emergent transcatheter arterial embolisation of the feeding artery was performed (fig. 1e). Intralobular pulmonary sequestration may present in adulthood as massive haemoptysis http://ow.ly/EQNsf
