Abdominal ultrasound result showing that exploration and size of the right adrenal area was about 1.1 cm × 1 cm hypoechoic structure, with rich internal blood flow signal (blue arrow in A). Chest CT results showed many nodules in both lungs, and the largest nodule (yellow arrow in B) was located in the middle lobe of the right lung, with a size of about 8.2 mm × 7.0 mm. Abdominal CT results showed that the right adrenal gland was not clearly displayed and multiple enhanced nodules were found inside, with the largest having a size of 10.8 mm × 17.2 mm × 17.8 mm (blue arrow in C). CT angiography showed that the tumor lesion (blue arrows) was compressed adjacent to the inferior vena cava, and the right inferior adrenal artery had vascular branches (red arrows) into the tumor lesion (D and E)
