Pulmonary carcinoid lesions throughout the course of therapy (first column = 7 months prior to stereotactic body radiation therapy [SBRT]; second column = 1 month before SBRT, third column = 3 months after SBRT). The patient’s index left lower lobe (LLL; red arrow), left upper lobe (LUL; blue arrow), and right lower lobe (RLL; green arrow) lesions throughout the course of therapy. The first column demonstrates lesions during the time of treatment with lanreotide (7 months prior to SBRT). The second column displays the same lesions 1 month prior to SBRT treatment. The third column demonstrates resolution of the LLL and LUL lesions as well as stable size of the RLL lesion 3 months after SBRT
