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). 2 weeks later, after recovering from respiratory failure, lobectomy was performed because of persistent bleeding and mild fever despite antibiotics. A massive haemorrhage within the intralobar sequestra with a thrombosed feeding artery as a result of the intravascular coil was confirmed (fig. 1f ).
