目的 探讨颅面骨纤维异常增殖症的影像表现和病理特点.方法 回顾性分析42例经手术病理证实的颅面骨纤维异常增殖症,对其影像学表现和病理特点进行对比分析.结果 42例中单发型35例,多骨型7例.磨砂玻璃状改变是骨纤维异常增殖症特征性CT表现,占CT检查患者的79.3%,纤维异常增殖症的病理成分纤维和纤维样组织,在磁共振的T_1WI和T_2WI上均表现为低信号;如病灶发生出血、坏死或囊变,T_2WI信号也随之发生改变.结论 CT和MRI扫描对颅面骨纤维异常增殖症的诊断具有重要意义.
目的 探討顱麵骨纖維異常增殖癥的影像錶現和病理特點.方法 迴顧性分析42例經手術病理證實的顱麵骨纖維異常增殖癥,對其影像學錶現和病理特點進行對比分析.結果 42例中單髮型35例,多骨型7例.磨砂玻璃狀改變是骨纖維異常增殖癥特徵性CT錶現,佔CT檢查患者的79.3%,纖維異常增殖癥的病理成分纖維和纖維樣組織,在磁共振的T_1WI和T_2WI上均錶現為低信號;如病竈髮生齣血、壞死或囊變,T_2WI信號也隨之髮生改變.結論 CT和MRI掃描對顱麵骨纖維異常增殖癥的診斷具有重要意義.

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.
