Abstract:
Objective:To analyze and summarize the imaging characteristics and clinical follow-up results of Ewing sarcoma of bone.Methods:The imaging data of 23 patients with Ewing sarcoma confirmed by pathology who treatment in Drum Tower Hospital Affiliated to Nanjing University School of Medicine from May 2010 to October 2021 were retrospectively analyzed, and clinical follow-up was performed.Results:Of the 23 patients with Ewing sarcoma of the bone in this group, a total of 18 patients had follow-up results and 5 cases were lost to follow-up. Of the 18 cases, 6 cases died and 12 cases survived. The main cause of death was lung metastasis. There were 27 lesions in total, femoral diaphysis was the most common site of the disease; bone structure destruction and soft tissue mass shadows could be seen in the images of each lesion. Periosteal reaction could be seen in most of the lesions (92.59%, 25/27). There were certain differences in signs of bone destruction and periosteal reaction between different bone types.Conclusions:The imaging of Ewing sarcoma of bone mainly manifests various types of bone destruction, soft tissue masses and periosteal reactions. Ewing sarcoma of bone is mainly bone marrow metastasis and lung metastasis, and lung metastasis is the main cause of death.
