High resolution chest CT (HRCT) and digital subtraction angiogram before and after the BAE in case #2. A 33-year-old male patient with 10 years of smoking history had cryptogenic hemoptysis for one week with approximately 100 mL of blood each time. A and B: High resolution chest CT showed patchy and ground glass image in the right lung, indicating accumulation of blood in the alveoli. C and D: Digital subtraction angiograms from a selectively catheterized right bronchial artery, showing hypertrophied right bronchial artery and branches as well as hyper-vascular lesions. E: Digital subtraction angiogram after embolization, showing no residual flow to the lesion area
