a CT image showing the presence of varicoid bronchiectasis and parenchymal infiltration around the basal anterior segmental branch line of the left lower lobe. b CT image showing resolution of parenchymal opacity. c Fibreoptic bronchoscopy showing two small nodular neoformations in the sub-segmental branches of the lower right lobe. d Biopsies (×20 magnification): on the right there are two fragments with necrosis, on the left two fragments with haemorrhage, in the form of blood with fibrin, hemosiderin and organizing pneumonia. e and f Necrosis and bleeding are best seen at higher magnification, ×200 left and ×100 right, respectively
