Abstract: Objective To investigate the characteristics of imaging signs of giant cell tumor(GCT)of the hand and foot bones.Methods The clinical,X-ray,CT and MRI images of 18 cases of GCT of hand and foot bones diagnosed by pathology were analyzed retrospectively.And compared with 54 cases of long bone GCT imaging manifestations.Results Among the 18 GCT cases of hand and foot bones,there were 8 cases of hand,10 cases of foot,including 12 cases of short tubular bone and 6 cases of tarsal bone.All lesions were dilatant osteolytic bone destruction involving the joint surface,in which the short tubular bone GCT showed central growth,the tumor occupied the entire wide diameter of the bone,the lesion range was long,consistent with the bone axis,easy to invade the surrounding soft tissue,sclerotic edge,bone ridge,lobed and periosteal reaction were rare,and prone to recurrence after surgery.The GCT of tarsal bone and short tubular bone showed eccentric growth,and there was statistical difference(P<0.05).The probability of pathological fracture in GCT of long bone was significantly greater than that of short tubular bone.There was no significant difference between the two groups in swelling growth,involvement of bone end and ethmoid sign of bone cortex.Conclusion Compared with long bone GCT,hand and foot bones are rare occurrence site of GCT,which is more aggressive than long bone GCT and prone to recurrence after surgery.Full attention should be paid to its imaging characteristics to provide more accurate image information for clinical treatment strategies.
