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 (x20 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, x200 left and x100 right, respectively

The patient underwent a new chest CT scan: around the basal anterior segmental branch line of the left lower lobe, mild varicoid bronchiectasis and distal parenchymal infiltrate were present, in addition to mild signs of airway inflammation in the right lower lobe (Fig. 1a). A fibreoptic bronchoscopy showed two small nodular neoformations in the sub-segmental branches of the same lobe (Fig. 1b). Some large fragments of peribronchial pulmonary parenchyma (Fig. 1d) presented an area of haemorrhagic necrosis, with blood and fibrin, hemosiderin deposits and organizing pneumonia (Fig. 1d, e). On December 18, a new chest CT showed a complete resolution of the parenchymal opacities (Fig. 1f).
