A chest radiograph identified a shadow in the lower zone in the left lung, and subsequent CT scan confirmed the presence of a 2.5 x 2.5 cm mass in the lower left lung and multiple mediastinal lymph nodes (Figure 1(a) and (b)).
CT Scan image following the patient taking CBD: (a) marked regression of the left lower lobe mass leaving a small irregular residual linear band, and (b) striking regression of the mediastinal lymph nodes.

The patient had a further CT scan in November 2017 which revealed near total resolution of the left lower lobe mass with only a small area of residual spiculated soft tissue remaining (1.3 x 0.6 cm) and a significant reduction in size and number of mediastinal lymph nodes (Figure 2(a) and (b)).
