Figure 1 Radiologic and pathological examinations of the patient with intravesical gemcitabine-induced pulmonary toxicity. A: Ureterography indicating left urothelial obstruction; B: Gross appearance of urothelial carcinoma after laparoscopic radical nephroureterectomy with bladder cuff excision; C: Pathological examination by hematoxylin and eosin staining showing invasive urothelial carcinoma with infiltration to the muscular layer (× 100); D: Chest computed tomography (CT) scan showing bilateral emphysema and bullae 3 mo before the onset of gemcitabine-induced pulmonary toxicity; E: Chest CT scan on admission showing bilateral patchy infiltration accompanied by preexisting emphysema and bullae; F-I: Chest CT scan on the 11th day showing worsening of the patchy infiltration with foci that were more consolidated after empirical antibiotic therapy, resulting in worsening of the respiratory distress; J: Pathological examination by hematoxylin and eosin staining showing organizing pneumonitis in the percutaneous lung biopsy of the consolidation focus (× 100); K: Chest CT scan 1 mo after admission showing obvious absorption of the multiple consolidation foci after tapered corticosteroid therapy.
