case_images: PET/CT (p17102705). PET/CT (p17102705) of Baotou Central Hospital showed hypermetabolic mass in left hilar area, which was considered to be malignant with multiple lymph node metastases in left supraclavicular region, right subclavian region, uppermost mediastinum, paratracheal, anterior vena cava, retrotracheal vena cava, paraaortic arch, aortic window, subcarina, and bilateral hilar regions, and metastatic tumor in both lungs. The left lung biopsy showed small cell carcinoma.

case_images: PET/CT (p17102705) (Fig. 1) of Baotou Central Hospital showed hypermetabolic mass in left hilar area, which was considered to be malignant with multiple lymph node metastases in left supraclavicular region, right subclavian region, uppermost mediastinum, paratracheal, anterior vena cava, retrotracheal vena cava, paraaortic arch, aortic window, subcarina, and bilateral hilar regions, and metastatic tumor in both lungs.
case_images: PET/CT (p17102705-2). The mass of hypermetabolic soft tissue in the left hilar region disappeared compared with the 2017.10 PET/CT result; the hypermetabolic enlarged lymph nodes in the original mediastinum and left hilar almost disappeared; there were multiple slightly hypermetabolic lymph nodes in the mediastinum and right hilum, some of which were accompanied with calcium deposition and possibly due to inflammatory proliferation, so regular follow-up checks were required; the left intrapulmonary metastasis disappeared; no abnormal uptake of imaging agents was found in the right 10th rib and left occipital lobe, though regular check was still required.

case_images: As shown in the PET/CT (P17102705-2) scan performed on May 28, 2020 (Fig. 2), the mass of hypermetabolic soft tissue in the left hilar region disappeared compared with the 2017.10 PET/CT (p17102705) result; the hypermetabolic enlarged lymph nodes in the original mediastinum and left hilar almost disappeared; there were multiple slightly hypermetabolic lymph nodes in the mediastinum and right hilum, some of which were accompanied with calcium deposition and possibly due to inflammatory proliferation, so regular follow-up checks were required; the left intrapulmonary metastasis disappeared; no abnormal uptake of imaging agents was found in the right 10th rib and left occipital lobe, though regular check was still required.
