摘要

This paper reviews the imaging appearance of benign and malignant bone tumors of the maxillofacial region.A benign bone tumor commonly appears as a well circumscribed lesion.The matrix of the tumor may be calcified or sclerotic.Malignancies often display aggressive characteristics such as cortical breakthrough, bone destruction,a permeative pattern and associated soft-tissue masses.Computed tomography scan is an excellent imaging modality for accurate localization of the lesion,characterization of the tumor matrix and detection of associated osseous changes such as bone remodeling,destruction or periosteal reaction.Magnetic resonance imaging is of limited value in the evaluation of maxillofacial bone tumors.
