Diagnosis: angiosarcoma. Technique: contrast-enhanced chest CT. Description: A 64-year-old man with no history presented with progressive shortness of breath. The initial contrast-enhanced CT scan (a) to rule out pulmonary embolism shows a well-delineated pleural-based oval lesion (arrow) in the base of the right lung. Findings are relatively aspecific. Follow-up CT examination 4 weeks later (b) shows prominent disease progression, with a large amount of fluid. Despite the relatively short time interval, there is a marked increase in pleural lesions, with widespread focal contrast enhancing pleural lesions in the right hemithorax. The rapid and aggressive progression points to the possible diagnosis of angiosarcoma, which was histologically confirmed
