Abstract: Objective To investigate the different manifestations of postoperative recurrence and scar of bone and soft tissue tumors on CT and MRI, and to evaluate the clinical diagnostic value of ultrasound in differentiating postoperative tumor recurrence and scar formation. Methods Fifty patients with suspected recurrence of bone and soft tissue tumors treated in the Department of Bone Oncology of the Third Affiliated Hospital of Southern Medical University from January 2016 to July 2021 were retrospectively analyzed, aged 8-84 years, with an average age of (36.2±19.5) years, 21 males and 29 females. Forty-two cases were located in limbs, 6 in pelvic ring and 2 in spine. All cases were examined by ultrasound, CT and MRI. One deputy director or chief physician of the ultrasound department and the radiology department mainly engaged in the musculoskeletal system. On the basis of CT, ultrasound and MRI were diagnosed respectively. All cases had pathological results of surgical resection or puncture biopsy. Results Among the 50 cases, 40 cases were diagnosed by pathology as recurrence and 10 cases as cicatrix . The sensitivity, specificity and accuracy of ultrasound diagnosis were 97.50%, 90.00% and 96.00% respectively. The sensitivity, specificity and accuracy of MRI were 92.50%, 40.00% and 82.00% respectively. The specificity and accuracy of ultrasound were higher than those of MRI, there were statistical differences in specificity and accuracy between ultrasound and MRI (P<0.05), the sensitivity was the same, and the difference was not statistically significant (P>0.05). The specificity of ultrasound in patients with internal fixation (85.71%) was higher than that of MRI (42.86%), and there were statistical differences in the specificity in patients with internal fixation between ultrasound and MRI (P<0.05).  Conclusions  Ultrasound can improve the diagnostic efficiency of bone tumor recurrence in the differential diagnosis of postoperative recurrence and scar formation of bone and soft tissue tumors, especially when the internal fixation has an impact on CT or magnetic resonance imaging, which is worthy of clinical promotion.
