Abstract:
Objective To analyze the imaging manifestations of chondromyxoid fibroma,so as to improve diagnostic accuracy.Methods The X-ray,CT and MRI manifestations of 8 cases with chondromyxoid fibroma confirmed by surgical pathology were analyzed retrospectively.Results All of 8 cases were in the long tubular bones.X-ray showed oval,well defined,eccentric,radiolucent lesion with surrounding sclerosis.The thick dense bony or coarse reticular septation were seen in 6 cases.CT scan showed osteolytic,surrounding sclerosis,and 1 case with foci of calcification.MRI images showed a low or medium signal on T1WI,high signal on T2WI,1 case with a equal T1WI and slight high T2WI signal intensity peripheral rim around.Two cases with diffused enhancement on T1WI after intravenous injection of gapentetate acid meglumine injection and a peripheral liner enhancement in 1 case.Conclusion Chondromyxoid fibroma has certain imaging characteristics,but should be combined with X-ray,CT and MRI to differentiate from other bone tumors with similar imaging manifestations.
