CT and MRI images of the anterior abdominal wall mass (A, B) and liver metastases (I, J) before immunotherapy. MRI images of the anterior abdominal wall mass (C, D) and liver metastases (K, L) after immunotherapy. Comparison of CT images of metastatic tumors in both lungs before (E, F) and after immunotherapy (G, H).

CT showed large metastases in the anterior abdominal wall and multiple metastases in the liver ( Figures 1A, I ). Chest CT showed multiple metastatic tumors in both lungs ( Figure 1E ). After 2 cycles of treatment, chest CT and abdominal MRI showed that the metastatic tumors in both lungs, anterior abdominal wall mass and liver metastases were larger than before ( Figures 1B, F, J ). After three cycles of treatment, reexamination by abdominal MRI showed no significant changes in the anterior abdominal wall mass and liver metastases ( Figures 1C, K ), but chest CT showed that multiple metastases in both lungs were smaller than before ( Figure 1G ). Reexamination after 3 cycles of treatment indicated that some of the lung lesions were smaller and some were larger than before ( Figure 1H ), and the anterior abdominal wall masses were the same as before ( Figure 1D ), but the liver metastases were significantly larger ( Figure 1L ).
