眼眶骨纤维异常增生症的多排CT诊断

目的:探讨多排CT对眼眶骨纤维异常增生症(FD)的诊断价值及临床意义.方法:回顾性分析2002年4月至2009年8月的该院(6例)及中山大学中山眼科中心(12例)收治的18例眼眶FD患的多排CT表现,7例取病变组织经病理证实,5例经手术后病理证实,6例具有典型的CT表现.结果:本组眼眶FD可单发(5例)、单骨多发(1例)或多骨(12例)发病,其中额骨12例,蝶骨5例,筛骨2例,颞骨7例.结论:多排CT能在轴位、冠状位、矢状位上显示本病的病变特征及范围,有助于本病的早期诊断及指导临床制定合理的治疗方案.

Multi-detector row computer tomography findings of fibrous dysplasia in orbital bone

PURPOSE: To evaluate the efficacy of multi-detector row CT (MDCT) findings in the diagnosis of fibrous dysplasia (FD) in orbital bone. METHODS: The MDCT manifestations of 18 cases of FD in orbital bone (6 cases from the 458th hospital of PLA, 12 cases from the Zhongshan ophthalmic center of Sun Yat-Sen university) collected from April 2002 to August 2009 were reviewed. Six cases were confirmed by biopsy, 5 cases were confirmed by operation and postoperative pathology, the remaining 6 cases were confirmed based on typical CT findings. RESULTS: FD in orbital bone could be originated from monostotic single lesion (5 cases), monostotic multiple lesions (1 cases) or polyostotic multiple lesions (12 cases). Twelve lesions were originated in the frontal bone, 5 lesions in the sphenoid, 2 lesions in the ethmoid, 7 lesions in the temporal bone.CONCLUSIONS: MDCT is very important in the diagnosis and treatment strategy of FD in orbital bone correctly. It help identify the location and extension of the lesions based on the axial plane, coronal plane and sagittal plane view.
