(a) Initial chest x-ray reveals an apical left lung partially excavated opacity (arrowhead) associated with a silhouette sign of the upper left mediastinum, consistent with secondary tumor infection. Note that owing to mass effect, there is right-sided tracheal deviation (arrow). (b) A control chest x-ray obtained 10 days later shows an unfavorable evolution as seen by an increased infectious tumor focus, progression of the excavated components (arrowhead), and occurrence of lingular opacity (asterisk)
