摘要
Abstract
[Objective] To improve the understanding of CT and MRI features of giant cell reparative granuloma of temporal bone and reduce misdiagnosis.[Methods] The CT and MR images of 4 cases of GCRG of temporal bone were analyzed,compared with their operation and pathology results.[Results] All the lesions of the 4 cases were located in the anterior and lower parts of the temporal bone with widely destruction.The CT images showed expansive destruction of bone with disruption of osseous shell,strip and punctate calcification and ossification in and around the lesion,and osteosclerosis of the adjacent bone,which consistent with the scope of the operation.The MR images showed a large patchy of low signal intensity on both T1-weighted and T2-weighted images,which showed heterogeneous enhancement after injection of contrast.Fibrous proliferation with multiple multinuclear giant cells and hemosiderin deposition were showed under microscope.[Conclusion] The morphological and pathological characteristics of recurrent intraosseous hemorrhage and parcels of granulation tissue in GCRG of the temporal bone could be reflected by CT and MR images,which has certain characteristics and is of important significance to the diagnosis of the tumor.关键词
