Figure 3:11C-choline positron emission tomography/computed tomography (a and b) showed supraclavicular (white arrow in a) and retrocrural lymph node (white arrow in b) at prostate-specific antigen <0.1 ng/ml. Diagnosis was confirmed on biopsy. Postchemotherapy positron emission tomography/computed tomography (c and d, white arrow in each) showed favorable treatment response
