A large 13.1*8.9*6.8 cm honeycomb-shaped tumor in the perihepatic and peri-splenic area is the most likely cause of metastatic and peritoneal tumors. Tumor pathogenesis is complex, usually related to heredity, infection, and decreased immune function. Tumors appear as a result of defects in the body’s immune barrier, leading to uncontrolled proliferation of specific cells in the body and resulting in malignant growth. The results of the current examination are imaging findings, and a localized biopsy is needed to determine the nature of the occupying lesion. It is recommended to further enhance the scanning examination, and consider arranging local pathological puncture biopsy to determine the tissue origin and malignancy of the occupying lesion, and consider the diagnosis together with the clinical symptoms, so as to achieve early discovery, early diagnosis, early treatment, and improve the cure rate of the tumor, and not to be negligent, so as to avoid the delay of the condition.
