Figure 1. A: Initial chest CT scan, a consolidative mass in RML and RLL with multiple hematogenous metastatic nodules in BUL. B: Chest CT scan before treatment with 250 mg gefitinib, more increased consolidative mass in the right lung field. C: Chest CT scan 6 months after treatment with 250 mg gefitinib, much improved consolidative mass in the right lung and markedly improved hematogenous metastasis in BUL. D: Chest CT scan 13 month after treatment with 250 mg gefitinib, no interval change compared with the previous CT scan.
