Abstract

PURPOSE
To describe MR findings of recurred giant cell tumor of bone.
MATERIALS AND METHODS
MR imagings of ten cases of pathologically proven recurrence of giant cell tumor were retrospectively analyzed. Location of recurrence, multiplicity of recurred tumor, signal intensity and homogeneity, pattern of gadolinium enhancement, soft tissue and articular surface involvement were evaluated.
RESULTS
Tumors were located in peripheral portion of previous operation site(80%). Six cases recurred as multiple lesions. Tumor showed low signal intensity on T1 weighted images(100%), high signal intensity on T2 weighted images(100%) and inhomogeneous peripheral rim enhancing pattern(75%). Soft tissue and articular surface involvement were also demonstrated.
CONCLUSION
We concluded that characteristic MR findings of recurred giant cell tumor could be helpful in early detection and precise evaluation of tumor recurrence.
