Imaging features and pathologic features of the patient. a Chest radiography shows focal round lesion with thick-walled cavity in the right upper lung. b Bronchoscopic picture of bronchial papilloma occluding the lumen of posterior segment of the right upper lobar bronchus. c Computed tomography shows a focal lesion of 4.0 × 4.4 cm in the posterior segment of the right upper lobe with broad-based contact to the pleura. d Computed tomography shows patchy calcification and marked contrast enhancement. Biopsy of the specimen shows bronchial papilloma in e (hematoxylin-eosin stain, ×100) and f (hematoxylin-eosin stain, ×40). Histopathological examination of the right upper lobe diagnoses of pulmonary sclerosing hemangioma, this image shows the solid areas in g (hematoxylin-eosin stain, ×40), h (hematoxylin-eosin stain, ×100) and i (hematoxylin-eosin stain, ×200). Histopathological examination of the right upper lobe diagnoses of pulmonary sclerosing hemangioma as following. j (hematoxylin-eosin stain, ×40) and k (hematoxylin-eosin stain, ×100) show the sclerosing areas
