Imaging and Pathology Features of Fibrous Dysplasia in Craniofacial Bone / 实用放射学杂志

ABSTRACT

Objective To explore the imaging features and pathological characteristics of fibrous dysplasia of craniofacial bone. Methods 42 cases with fibrous dysplasia of craniofacial bone confirmed surgically and pathologically were retrospectively analyzed. Results There were 35 cases with single bone involved and 7 cases with poly-bone involved. On CT images, the lesions appeared as glass-like change(79.3%). The main pathological components of the lesion were fiber and fiber-like tissue, which were low signals on both T_1 WI and T_2 WI, and the signal intensity was changed with the accompanied by hemorrhage, necrosis or cystic degeneration. Conclusion CT and MRI are the effective imaging modality in diagnosis of fibrous dysplasia of craniofacial bone.
