Abstract:
Objective To analyse the MRI appearances of giant cell tumors of the bone and the relationship with their pathologic bases.Methods Histologic examinations were conducted in 21 cases,and their correlations with the MRI appearances were further evaluated.Results There were 3 cases of the Ⅰ grade,3 cases of the Ⅰ～Ⅱ grade,13 cases of the Ⅱ grade,2 cases of the Ⅲ grade of the giant cell tumors.Most tumors were composed of solid content that presented sligthly low to intermediate signal intensity on T 1WI,sligthly high to high signal intensity on T 2WI.The minority of the tumors were composed of the half of the solid and cystic contents expectively.Specific tumors was mainly composed of cystic content or combined with fluid-fluid level on T 2WI.Soft tissue masses were found in 8 cases.Conclusion The location and their extension into the soft tissue of the tumors can be clearly demonstrated on MR imaging,but there is no relationship between the grades of the tumors and their MRI appearances.
